This is a VPN problem, not a bridging problem.  What you basically need
to do is replace the default route on your system with a route through
your VPN tunnel.  There are a couple of practical problems you can run
into when doing this, but it is quite possible.  There's a fair amount
of documetnation about setups like this in the FreeS/WAN docs, and in
their mailing list archives...you basically need to setup a tunnel with
the far end being 0/0 (the whole internet), and the near end being your
existing network.

NOTE:  There's another feature that you may find handy...look through
the FreeS/WAN documentation for "extruded subnet" configurations.  This
allows your remote systems to behave as if they were on a subnet located
at the far end of your VPN.
