One thing I was wondering though, mostly for my own curiosity, is what config you're using that shows the problem, and how does the problem manifest? I just put this in bird.conf: router id 192.168.88.2; protocol babel { interface "wg0" { type wired; port 1234; }; }; And then I ran: # pkg install bird2 # bird -d -c bird.conf And I didn't see any troubling error messages. But maybe it's more subtle than that? Jason
