Bridge interfaces?

This could be a stupid question so bear with me. I currently have a
server/client setup going and it works i can ping the WG addresses and they
can talk to one another. The client also happens to have a Tinc adapter
that goes to a larger network, is it possible to use wireguard to give the
server access to this Tinc through the client?

Hi,

Yes indeed this is possible. Enable ip forwarding (sysctl -w
net.ipv4.ip_forwarding=1), and then make sure you have the correct
routes set. You may have to add a few entries to your allowed-ips to
ensure that the network is okay with wireguard, or, perhaps easier,
would to just enable MASQUERADEing (iptables -t nat -A POSTROUTING -s
10.8.8.0/24 -o tinc0 -j MASQUERADE, where 10.8.8.0/24 is the wireguard
network.)

There are a lot of ways to skin the cat, and I suspect if you write
back with details of network segments and whatnot, there might be
others who might have their own useful opinions. Alternatively, you
can always ask in #wireguard on Freenode.
