I have followed this guide to build WireGuard "server" on Ubuntu 22.04 on Vultr. [image] How To Set Up WireGuard on Ubuntu 20.04 | DigitalOcean In this tutorial, you will set up WireGuard on an Ubuntu 20.04 server, and then configure another machine to connect to it as a peer using both …

Just tried adding back /24 and /64, same. For the two WG instances, one is on the router listening on 51820, while the other is on a remote server. So they won't be conflict.

As far as I can see the second tunnel does not have a listen port and then it might default to 51820?

Check IPv6 ping and traceroute from LAN clients. Collect and analyze runtime configuration from OpenWrt.

Thank you very much. # wg show interface: zion public key: xxxxx private key: (hidden) listening port: 42125 peer: xxxxx endpoint: [2001:19f0:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx]:51820 allowed ips: 0.0.0.0/0, ::/0 latest handshake: 1 minute, 24 seconds ago transfer: 71.72 MiB received, 2.…

I have just tried running the commands mentioned on the last reply of this thread: [image] How to do IPv6 over WireGuard (with LUCI)? Installing and Using OpenWrt There's another method based on PBR with IP rules that works for me quite well: https://openwrt.org/docs/guid…

[image] y2kbugleung: Vultr provides both IPv4 and IPv6. This seems to be getting way too complicated. I have done this with a Linode VPS without loading multiple routing tables or poking around in iptables/nftables. First, forget ULAs. Take a /64 out from your Vultr /56 and assign it (pref…

Thanks for your suggestion. May you instruct me how to "take a /64 and assign it to my LAN" please? This is the IPv6 from Vultr: [image] Thanks.

Looking further it looks like Vultr only gives customers a single /64. Which really isn't very useful if you want to set up a VPN server with IPv6 support. As I said I use Linode and they will issue /56 or /48 on request.

Now setting 0.0.0.0/0 and ::/0 with "route allowed IPs" on WireGuard interface works. However, unchecked "route allowed IPs" on the WireGuard interface, but managed with PBR does not work. 0.0.0.0/0 routes via WireGuard server, but ::/0 does not.
