That is also what I observed. Without IFF_MULTICAST I see the following error in bird's log: bird[8045]: babel1: Socket error: IPV6_MULTICAST_IF: Can't assign requested address bird[8045]: babel1: Cannot open socket for wg1 > Stefan - please let me know if those work for you. In my testing thus > far, things seem to work for me. After applying Toke's patch for bird and your Wireguard patch in a7a84a17faf784 everything is working as before (with minor config changes). Just for the record, my previous configuration looked like this (using POINTTOPOINT interfaces, I use ifconfig to set the peer address): > [Interface] > ... > Address = fe80::5/64 > PostUp = ifconfig %i inet 169.254.42.5/32 169.254.42.2 My new configuration without POINTTOPOINT, but only a single peer directly attached to other side of the wg tunnel: > [Interface] > ... > Address = 169.254.42.5/32, fe80::5/64 > PostUp = route add 169.254.42.2 -iface %i So for me everything works as expected again. A big thanks to all of you for figuring out what was going wrong and getting it fixed so quickly. Kind regards, Stefan
