site-to-site (gw-to-gw) bridged vpn

Hi all,

I am not a new linux user, but I am new to configuring VPN systems. I have two remote networks, one on 192.168.0.0/24, the other on 192.168.1.0/24. Each site has a router with VPN passthrough. I would like to bridge the two sites, so that we can share broadcast traffic (Among other functions, we want to be able to play LAN games, so broadcast would be necessary).

Can anyone point me to a good tutorial or howto? Google doesn’t seem very helpful in this area. If there is no such thing, can anyone give me some steps to getting this running/learning to get it running? Thanks for everything!
