I have openswan 2.1.1 running on a slackware 9.1 box using a patched 2.4.22 kernel.
This machine only has one nic and has a static IP address and sits behind a Cisco 1720 router using NAT.
My original though to test openswan was to see if I can get a machine on the same network to connect. [this is an XP machine] I am able to connect fine put of course cannot ping anything.
I assume this is because the Openswan server only has one nic. However, before I install a second card I want to be sure that I have the topology right in my head.
Also when I attempt to connect from outside what setting changes to I need to make to the NAT on the router to let the "road warrior" connect?
