I want to configure my Ubuntu Laptop as a "Roadwarrior". On the Zywall USG 20 i configured IPSec. What IPSec Client is the best for Ubuntu 12.04?
I was trying to set up a manually-keyed connection via ipsec-tools between two ubuntu 12.04 servers, following this simple tutorial, but one of that two servers, has just a range of ports 3000 .. 3100 ...
Is it possible to create a separate device (like tun made by openvpn) for ipsec? If yes how can I do it?
Complexity of installation of IPSec is not an issue. I would like to know which one will provide a faster connection for tunneling.
