Well, I finally got NAT to work for short periods of time. I have a static 1-to-1 mapping, but for some reason, the connection drops after a while. The host (192.168.0.10) is a Windows XP laptop connecting to a Cisco 2924XL switch, which in turn connects to a Cisco 3640 router (192.168.0.1 internal, 64.171.42.211 external).
Any ideas why this might be happening?
