[Openswan Users] Multiple tunnels

[Bgs]

  Hi all,


I was wondering, which is the best way to achieve complete transparency 
between all networks in the following setup:


netA - gwA - Internet - gwB - internet - gwC - netC
                          \- netB

(For those with non fixed width chars: Three networks are given: netA, 
netB, netC. They all have their VPN capable gateways (gwA, gwB, gwC 
respectively). I want to connect netA with netB and netB with netC, but 
I also want netA to be able to reach netC through A-B + B-C tunnels, 
without A-C tunnels.)

Bye
Bgs
