Openwrt ipv6 wan I get an IPv6 assigned by ISP. My ISP is Free (France) and the modem-routeur is a Freebox mini server, on which I I'm having trouble with my IPv6 WAN connection. Just learning bits and pieces about ipv6. 1' option After you install OpenWrt on your Router you should do a IPv6 Routing Benchmark to know how well it performs routing of IPv6 network packets between your local network (LAN) to your internet service provider (WAN) should it already provide IPv6 connectivity. I've got TL;DR Problem: No IPv6 connectivity despite valid addresses and routes from some wired/wireless clients. { "kernel": "5. In this example, we will use 3 routers and 2 client PCs. in past for IPv4. I have no problem connecting w finally, i reuse 17. 06. According to their FAQ they use SLAAC to assign IPv6 addresses: Log into TP-Link router through the gateway in your browser. But no ipv6 address,when I checked it by http://test-ipv6. I have a dual stack connection to the Internet from my ISP, with both a type B NAT for my I don't know exactly when it stopped working. com (from the router) works. But since every 6in4 packet has to go through the WAN interface as well, how can it be that traffic on WAN6 is higher than on WAN? Or is that traffic somehow excluded from WAN statistics? Hi, just installed OpenWrt on my router (Netgear R7800), and now I am entering the world of IPv6 (only late by 20 years or so!). My LEDE router connects these two, the "home net" being behind the wan port and the "desk net" behind the lan ports. However, the routing table shows default gateway on WAN interface: root@rb760igs:~# ip r default via 37. We're a small business and had to switch our fiber provider. 16 KB. I am using the firmware with openwrt I'm trying to get IPv6 connectivity too. The unexpected (at least to me) side effect of this, is I configured my ipv6 wan (it is a native ipv6 connection provided via dhcpv6 from my FritzBox which gets a /56 Prefix from my ISP). Implement multi-WAN based on PBR with netifd. 1 with a support agent, so nothing seems to be wrong on that end. I have been trying for a few weeks to get my stock 21. 2 [VLAN 2 on eth1, which is the LAN port] interface lan device eth1. If I look at the traffic count, I can see that the traffic for WAN6 is higher than for WAN. config dhcp 'lan' option interface 'lan' LAN get ipv6, but cannot access any website: cirn09@nas:~$ ip a show dev enp1s0 2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 7c:83:34:be:20:6b brd ff:ff:ff:ff:ff:ff inet 192. A Double Natted DMZ config is needed. trendy May 15, 2019, 9:47am 15. The router's address is: 2600:XXXX:7005💯d144:718d:e219:dc2e/128 And it received an IPv6-PD range of: 2600:XXXX:6c3f:7f00::/56 I have a linux server inside my network, and I I use openWrt on a router, in a straightforward router mode (behind ISP’s modem in bridge mode). Here is my solution, A catch-all IPv6 traffic rule to block IPv6 inbound is done with: config rule option name 'DROP IPv6 >' option family 'ipv6' option dest 'lan' option target 'DROP' option src '*' For LuCI users, From ANY ZONE for option src '*' Of course, should you want to allow ISP hands out only a /64 (I have tried requesting /56 and /60 through wan) IPv6-PD: 2::/64 2 interfaces, only one of them works fine, which is LAN I want the "guest" network to also be part of this Ipv6 subnet, even thouhg they are in diff ipv4 subnets, their firewall zones are different I have tried making wan6 the "master" interface for handing out prefix delegates and Hi all, After struggeling a bit to get IPv6 to work I realised that in contrary to IPv4 you need to explicitly allow certain ICMPv6 types on wan side and lan side (I had router access blocked on most VLANs, which automatically includes ICMPs). com/. Sorry that it's probably not the first or second time this comes up but I tried to follow all previous posts and I still get IPv6 working. I'm currently trying to connect a OpenWrt router to this modem. How do I enable the Intranet to access the Internet properly /etc/config/network config globals 'globals' #option ula_prefix 'fd00🔢5678::/48' config interface 'lan' option type 'bridge' option ifname 'eth0. This is understandable: mwan3 deals not only with fail-over, but also with load-balancing, and for load-balancing the decision regarding the choice of the source address must be delegated to the router on a per-connection basis, and therefore the I have a /64 prefix (damn ISP 🤡 ) , like many of us becuse of unlimited ISP greed (that is the only thing that they provide an unlimited amount of). Connecting to my ISP using PPPoE. When it comes to clients though, they get IPv6 addresses but no Router is set. ISP router>> openwrt >> wired + wireless clients. EDIT: All sorted. Hi, i know is Hi, i know is already discussed but i find not a real solution . The (non-LEDE) home net router which also provides access to the internet and the LEDE router acquires a global ipv6 prefix via PD from the home net router. 1 (the only vlan on eth1). Now it seems like the ipv6 given is static. But I want to be able to access the OpenWRT router from my internet However, I can DNS and ping via IPv6 from my computer if I am connected directly to the modem. OpenWRT has suited my needs, so I bought an EdgeRouter X and installed OpenWRT. A common example convention is wan and wan6 (default with OpenWrt), along with an additional WAN interfaces such as wanb and wanb6 etc. I talked to my ISP, we found out that dhcpv6 on wan interface was configured to send dns release message when the router/network was restarted. My devices gets assigned local ipv6 addresses by the Client Devices unable to get ipv6 address - OpenWrt Forum Loading You can then use the IPv6 preference option on your OpenWRT wan interface to specify which prefix is the preferred one for when both WANs are online. com Ping request could not find host google. This has been working as desired for about a month, but this morning at about 7:15am local time on Mar 23rd (according to my network monitoring), IPv6 stopped working for all devices on all VLANs. IPv6 doesn't work on my LAN port, and after running tcpdump not just on the internal interface but the WAN Greetings forum I am having no luck blocking inbound IPv6 to my lan. The interface lan0 has a public IPv4 address and the other 3 interfaces (lan1, lan2, and lan3) are bridged into br-lan and use NATed range 192. My ISP gives the wan interface single /128 IP, two DNS addresses and /64 PD all via DHCPv6. my ISP is pppoe based, and they give me a static /56 prefix. 2, static config, Only IPv6 addresses are obtained in the cellular dial, but only IPv4 addresses are available on the Intranet. 103", "host I operate two networks here, my "home net" and my "desk net". logread shows that I get as far as "pppd 2.

It's running BIND DNS and the ISC DHCP server adds client names and addresses to the local DNS. Everything is configured fine so far - I guess: Public Internet --> OpenWRT eth0 public IPv6 address, public IPv6 prefix CGNAT IPv4 address LAN --> OpenWRT eth1 handing internal IPv4 addresses to different VLANs delegating public IPv6 prefix into Hi! I want to ignore the DNSs advertised by the ISP. Now I have the following script as a service and it's I want to open the port 80 and 443 in IPv6 to my local device. My OpenWRT router receives an IPv6 /64 address from my ISP router (WAN IPv6 interface on my OpenWRT router is set to DHCPv6). 10. the ipv6 does not have NAT. 拨号获取 IPv6. My setup looks like this: Internet -> WAN port of internet router, LAN Port of internet router-> WAN port of OpenWRT router, Device connected via wifi to OpenWRT router The setup works as it should. com returns 10/10 for each of them.

From the ssh-shell at the router i`m able to do a dns-request: <details><summary>dns-request</summary>nslookup Hi all, I have been using openwrt in the ipv4 world, and recently transitioned into the ipv6 world. IPv6 is enabled and a tcpdump on the WAN interface does show outgoing DHCP6 solicit packets but no response from the ISP. My ISP uses ipv6 via 6rd, as i have this option in the control panel: Right now I'm able to ping ipv6 addresses from the router. So wan get’s an ipv6 from the isp. If that isn't working, more than likely, your ISP doesn't support IPv6. I use the relay package and followed the tutorial there to relay my main wireless network: I also configured IPv6 and it's working relatively well, apart from a tiny thing: when I start my router, I wouldn't get IPv6 by default, I need to restart an interface. I have a "SFR Box 8" connected in fibre on the wan side and Ethernet on its LAN side. What are the key steps for getting both ipv4/ipv6 on an WiFi WAN For my internal network, I have all IPv6 deactivated. But I can from Luci - Diagnostics window - IPv6 ping & IPv6 traceroute and receive responses. I read the LEDE ipv6 basics but still can not figure out what is wrong. 2 on a TP-Link Archer C5 v1.

DaddyKwool November 27, 2021, 12:35pm 3. 0/24 subnet mask that has connectivity to the internet. eth1 is WAN, eth0 is LAN. The Dynamic DNS module of OpenWRT support several methods to determine the IP address that should be registered, but for IPv6 servers it is kinda non-obvious how to like a given ipv6 port 1978 should be opened through the openwrt router and the wan. ipv6=0' uci set 'dhcp. By default it uses ipv4 connection, but does not get an ipv6 address. After lots of messing about. Looking to set up IPv6 - currently disabled on the WAN side - but the docs seem unclear in places, and I couldn't find answers searching: Its my understanding that for a PPPoE connection like mine, I change wan Yes both LAN and WAN are set to relay, with the "master" bit set on WAN. Anyways I am trying to configure a dual stack static ip assignment. But the LAN interface is getting Hi all, I'm new to using IPV6 and seem to be struggling with problems with the basic set up. Hi! My Fiber ISP offers an IPv4 and IPv6 using PPP(oe).

I'm revisiting a topic from a few months ago, though with a bit of a broader scope to see if I'm able to get an answer. NDP stands for the Neighbor discovery protocol. For an uplink with native IPv6-connectivity you can use the following example configuration. It will work both for uplinks supporting DHCPv6 with Prefix Delegation and those that don't support DHCPv6-PD or DHCPv6 at all (SLAAC-only). I've tried to use: option ipv6 auto But the spawned WAN_6 With the mwan3 package, using IPv6 is not very nice: https://openwrt. I've tried to setup IPv6 with my ISP.

Again, this is how openwrt is set up by default on this I have a rather special setup (advertising public IPv6 prefixes on both LAN and WAN port, which I get through HE tunnelbroker). I guess that would be a good idea to explicitly add a list of ICMPs to allow in [OpenWrt Wiki] IPv6 configuration ? Ramon I want to use my WR841ND with OpenWRT as an IPv6 tunnel endpoint (HE Tunnelbroker) and publish the RA on the same WAN-Port that the router is connected to the internet via IPv4. 255 scope global dynamic enp1s0 valid_lft 43198sec preferred_lft 43198sec inet6 HI i've been trying to setup ipv6 with no luck, i followed this tutorial Also, i dont know what IPv6 assignment length to use, my router show this on overview IPv4 Upstream Protocol: Static address Ad i'm relatively new to ipv6.

In this configuration (which is typical for 4G/5G LTE connections) the LAN will not actually hold a GUA IPv6. I have a fresh install of OpenWRT, I updated the LAN bridge to use the 192. 5. I have to do it this way because I don't want all devices in the network be connected via the WR841ND, but to the main router. (well, i think, but i cannot really verify this because logread doesn't contain anything ipv6 related when i ifdown wan && ifup wan why?) my desired outcome is to have my router be reachable on a fixed ipv6 address under my domain name (for wireguard configured with a The PC gets an IPv6 address by OpenWRT. If I enable DHCP relay mode on both WAN and LAN interface, my local clients also receive /64 GUA and My ISP provides IPv6 access with a dynamic /56 prefix (say 24aa:bbcc:ddee:ff00::/56). Aside from the many reasons that this support should be on and the direction everyone should be moving which I agree with, I'm looking to understand Hello, I need some help: I set up a small computer with two NICs running OpenWRT as my main router. the policy works only for ipv4 with priority to wanb. ula_prefix Is this the same as the Luci: Interfaces WAN, advanced settings Any hints as to why the following config doesn't work on a self compiled image, but ok on official? The only clue i have is that proto gets set to "none" in ifstatus, whereas in the working version it gets set to "dhcpd6 As for me, I decided to set up some basic IPv6 in my LAN just to test things out, have an ability to test my own apps over IPv6, and, well, be prepared for the future, you know. Are you able to ping IPv6 services? Say, what does. Machine is RPi 3B+. The new provider came and installed what appears to be a terminating gateway/router (a Cisco Catalyst 3650). So, the OpenWRT router definitely knows the route to fd00:a:b::/48, as it's possible to speak to client 1 from the OpenWRT's wan address. OpenWRT is v4. However, for IPv6, it needs NAT or NPT. So, an OpenWrt router behind an IPv6 NAT will not announce the default route through itself until you set the default route announcement in the LAN settings to forced in /etc/config/dhcp:. I have to do it this way because I don't w Hey there, I am currently trying to automatically and dynamically assign an IPv6 GUA /64-subnet to my OpenVPN server running on my OpenWRT router. I have noticed that my WAN6 port now has a routable address (2a0e:xxxxx) on the status page where it didnt previously Can anyone help me out? My provider finally is supporting public IPv6 addresses on the router (when the modem is in bridge mode) So I started implementing it, I have a complicated network (used for testing and playing around with multiple daisy chained routers running DDWRT and OpenWRT) That all seems to work with PD down the chain, possible as my ISP delegates me a /56 prefix 🙂 If you are going to use the WireGuard interface similar to an IPv6 WAN, then you need two IPv6 prefixes, both on the "WAN" interface which is wg_ipv6 in your case, and a separate IPv6 prefix that's routed to OpenWrt and can Internally they can log in, but they cannot access the Internet via the OpenWrt router. Ipv6 works when clients are connected to ISP router, but does not when connected to openwrt. That is, the ethernet port plugs into a WAN connection, and the Pi sets up a WiFi AP for other devices to connect to.

I think that he got it via router advertisement and SLAAC because i disabled DHCP at the LTE-modem. After PPPoE dialing, a WAN_6 virtual dynamic interface (DHCPv6 client) will be generated. Maybe someone will write an add-on for the GUI, or Got IPv6 from ISP on WAN, but cannot get it on the LAN interfaces. Enable IPv6 NAT or NPT and disable IPv6 source filter if your routing configuration. To achieve this, i've set option ra_management '2', works great. Provide a simple failover method Hello every one, I have two wan interface, both have ipv4/ipv6, I use wan1 as my default route , and use wan2 for some other customized route. Is there any different between DSA and swconfig? And is it OpenWrt default config is very good with IPv6. Configure a static DHCPv6 lease and add a redirect using the ULA address. If you still want to use IPv6 in your LAN, then you can configure OpenWrt as an IPv6 NDP proxy between the WAN and LAN zone. There's no issue with internet access. Hi, i know is already discussed but i find not a real solution . 6 with the same configuration, problem “solved” my isp provide ipv6 var SLAAC recently my win10 PCs often lose the default route (::/0) after the advertised router lifetime (1800s) so i add a scheduled task "*/20 * * * * /etc/init. I've PPPoE with IPv4 and IPv6 support, the WAN interface is configured for PPPoE and automatically a new Virtual Dynamic Interface appears for IPv6 WAN. But I do not get a 'global/routable' IPv6 address. While I can get by with Dynamic DNS for now, I'm concerned that once they enable IPv6 that any prefix delegations will be unstable if I'm renewing/releasing leases, and that will cause me trouble with some static I want to use my WR841ND with OpenWRT as an IPv6 tunnel endpoint (HE Tunnelbroker) and publish the RA on the same WAN-Port that the router is connected to the internet via IPv4.
