[Openswan Users] OpenSWAN with only one interface

[arno van der walt]

Hey Guys

Coming from a Cisco perspective I know it is impossible to terminate a VPN 
tunnel on one interface and then route traffic out that same interface, 
effectively you always need an outside and an inside interface.

I did go through all the mailing list archives but couldn;t find anything on 
the topic...maybe because it has such an obvious answer but here goes.

Can i run OpenSWAN with only one interface?
Example config:
left= 10.10.10.1
leftsubnet= 10.10.10.0

Or could I add a virtual IP on the same interface of say 192.168.1.1 and 
then do this:
left= 192.168.1.1
leftsubnet=10.10.10.0


Any help would be appreciated.

Thanks

Arno
