Address Translation Frustration »

I've been pulling my hair out on this, and I'm just about to throw in the towel. Before I did so, I figured I would see if anyone out there might know definitively if that's a good idea or not.

I'm working with a Cisco 2620. This router has address translation enabled on it, so that services on the internal network can be offered to the external network (the Internet). This is done through statements like this one:

ip nat inside source static 1.1.1.1 2.2.2.2

Where 1.1.1.1 is the internal address and 2.2.2.2 is the external address. This works fine, so long as someone from inside the network does not try to do something involving the address on the outside of the network while they are connected to the internal network. Lost yet?
