@uvok@woof.tech Sure lol if you can. I feel like my lack of understanding of ipv6 also is kinda not helping wg0: flags=209 mtu 1420 inet 10.36.21.1 netmask 255.255.255.0 destination 10.36.21.1 inet6 fd80:e621::1 prefixlen 64 scopeid 0x0 [cut the rest] /etc/wireguard/wg0.conf: [Interface] PrivateKey = (key) Address = 10.36.21.1/24,fd80:e621::1/64 MTU = 1420 ListenPort = 51820 [Peer] PublicKey = (key) PresharedKey = (key) AllowedIPs = 10.36.21.2/32,fd80:e621::a24:1502/128 Configuration on my phone has an IPv4 domain name, and AllowedIPs is 0.0.0./0, ::0/0. v4 obviously all works fine, v6 is hard to test cause no fucking apps understand v6 literals lol but I can ping my phone via the host's fd80:a24... link-local on wg0. But v6-only stuff like ipv6.tlund.se doesn't work at all. Do I need to setup routes for v6? I tbh just used pivpn.io which I think setup v4 routes, but idk this is where my knowledge ends xD edit: the host itself has working v6

    @ntoskrnl@furry.engineer soo, just to understand, the peer is your phone? Yeah, that's hard to debug stuff with, because you never see what's going on. To reach "public" IPv6 sites, you need Either an public IPv6 peer address (maybe from your VPS's prefix?) or you need to do IPv6 masquerading (which I would need to look up). In other words, you can't reach e.g. ipv6.ipinfo.io , with just a ULA prefix (fc00::/7).
