[Openswan Users] leftsubnet ...how to do the routing

[hans lux]

hi all,

i think i have a beginners problem
and hope you can help me out.

my box connects to two different vpns.

both connections are established.
the one connection has a leftsubnet of 192.168.0.0/24
which matches a physical network on device eth2 (192.168.0.1)

the other one is the problem now.

to connect, the vpn server (watchguard) expects 10.106.121.0 for
the leftsubnet. I don't have any interface in that network.

how do i tackle this?
do i need a virtual device ?

thanks,
hlux
