I'm having troubles with my Cisco 2610 (IOS 12.2(21)). I'm running NAT, which is working just fine, but recently I got a strange error when trying to connect a VPN-tunnel from inside the router to a network outside.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
