[Jose M]

Thanks Alonso!

Could you give me some hints how to create routes and iptables to get this working?

It's possible to create virtual nics.
Use #: ifconfig eth0:1 192.168.1.5 netmask 255.255.255.0
to make it permanent change the /etc/network/interfaces file.





then you need to create a route to send all packets from vpn to the new ip address, also need to check your iptables.
Good luck.

I need to create an ipsec vpn between an internal network behind a cisco router and
 an ubuntu server in the outside that is directly connected to the web (no 
router here).

Right now I've test openswan to create a client to gateway vpn an works as expected. Unforunately with this configuration I don't have two way traffic, the client sees the internal network, but the network can't see the client.




My knowledge of networks isn't the best, so I need to ask, is it possible to create some kind of virtual nics in ubuntu client server to simulate a gateway and an internal network (with only one machine) in this endpoint, so the machines in the internal network can see this client?




Thanks in advance!
