VPN / tunnel / remote bridging

I have the following problem. I need to set up some sort of remote
bridging between three networks.
I have 3 networks in 3 different geografical locations. Each of this
networks has computers on an 192.168.0.x subclass. They are connected
to the internet via a linux box (Proxy or Masquerading).
The main goal is somehow to unite these networks into one, so that the
computers on it (Win 9x,Xp, etc.) can see each other.
I read some tons of documentations on the net and I think I should use
FreeSWAN for the tunneling. I thought about bridging the internal
network and the remote network using the tunnel interface.
My question is how can I configure FreeSWAN so that it joins two (or
more) networks from the same class, because I've only seen
configuration samples where there were two different subnets.
If it isn't possible to do this, perhaps somebody can show me some
different kind of approach. Maybe I have to change the class or smthg
else.
I am basically open to any kind of advice.

Many thanks,
Alex

If all the gateways are Linux boxes, I'd use CIPE for tunneling.
It's lightweight and relatively easy to set up.

Been there - done that.

Thanks for the tip, I'll look into that. Could you send me some sample configs?
Many thanks,
