Hello everybody,

br0 (with eth0 eth1 eth3)
wg0 (

dhcp-helper to forward broadcast to ip?

I am looking for way to use a wireguard tunnel to route all traffic 
including dhcp broadcast from one network to an other network and create 
a form of a network bridge.

I got an working wireguard client wg0 ( that has a 
linux bridge br0 on the same system, so br0 and wg0.

I can not add wg0 to the bridge because bridging is layer2.

How can I use either ip route, nftables, iptables, etc to route all 
traffic on br0 to wg0.

I want to runnel an dhcp and pxe boot over the br0 to wg0.

Can someone share an example?

Kind regards,

Jelle de Jong
