Hello,

I'd like to setup an IPSec connection (both sides are m0n0s) between
Subnet1 and Subnet2. Nothing exotic so far.

Now I'd like to route all traffic from Subnet1 (for which m0n0-1 is the
gateway) through the IPSec tunel to m0n0-2 in Subnet2. Even if the
destination is somewhere out in the web.

m0n0-2 then routes all traffic to a Server/Router on Subnet2, which is
again nothing too complicated, as I can simply set it up as the next
gateway.

Now the only complicated part is the middle one, can I and if so any
hints on how do I set up the routing.

Example:
PC01 in Subnet1 opens the browser and surfs to some public website, 
the traffic goes to m0n0-1,
which sends it to m0n0-2, 
which sends it to a server on subnet2,
which then routes it into the internet.

I'm thankful for any advice,
Greetings
 Alexander Schaber
