[Openswan Users] ipsec tunnel interface and routes

[Maverick]

Hi,

I've made a tunnel between two networks A and B, on my end (A) I have
openswan and on the other (B) end is a cisco firewall.

I've tested the access and everything seems to be ok.

But there is a network C that must be accessed through a machine (B.254) on
network B that is making NAT to that network C.

My first question is, where is the ipsec tunnel interface? I run ifconfig
and only get my eth0 and lo.

When I make a traceroute to a machine on network B it goes directly.

So how I can i add route to network C saying that the gateway is B.254 ?
