I'm a bit confused about your configuration files - could you better
organize them and present including the underlying host they are on? From
the question, it's unclear as to whether there are multiple WireGuard
servers or a single server. I see you reference pinging 192.168.1.0/24 but
I do not see any configurations showing that CIDR.

You may need a masquerade or SNAT for your WireGuard (wg0/wg1) interface.
Otherwise, the forwarded packets will be from an invalid range/host and
discarded depending on the exact configuration.

I.e. if your traffic is coming into the server from client -> wg1 but
leaving (forwarding) to wg0 then you'll need a masquerade on wg0  iptables
-t nat -A POSTROUTING -o wg0 -j MASQUERADE
