I've been trying to bridge 2 office networks together for a few weeks now, both networks are just basically a dozen computers, each side has a NAS for the work data. I'm trying to make it so every system on each side can connect to both NAS units pretty much transparently (ie: map eachother as a network drive). I've fought with a TAP setup going router to router for hours on end and just can't get it to be stable with either 2x WRT54GLs or 2x RT-N16s on any VPN build, the routers consistently just drop all connections every couple minutes and become unusable until the VPN connection is cut. Has anyone ever successfully utilized a TAP VPN with Tomato or DD-WRT with stability? I can't seem to wrap my head around this and find this answer no matter how much I look: is there any way to bridge two networks together router to router with a TUN connection? Most guides or discussions are just pointing towards tunneling a single client through. I just want to be able to map the NAS on each end to every PC.
