info for wireguard

[Michele Salerno]

Hi,

i have installed ansible-wireguard-openwisp and i have the interface on server

wg0: flags=209<UP,POINTOPOINT,RUNNING,NOARP>  mtu 1420
        inet 10.253.0.1  netmask 255.255.0.0  destination 10.253.0.1
        unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00  txqueuelen 1000  (UNSPEC)
        RX packets 28  bytes 2552 (2.4 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 18  bytes 1896 (1.8 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

on babel i have this log

Interface wg0 has no link-local address.
setsockopt(IPV6_LEAVE_GROUP): Cannot assign requested address

i have question...

because the interface wg0 has no link-local address?

thanks.

Hi Michele,

I guess wireguard is not configured to use ipv6 link local by default, not sure if it's doable, it may be, however, it would be better to post this type of questions on Wiregard related support channels rather than here.
