I've struggled with this problem before and never really found a good solution and it's driving me crazy. The basic problem is how do I get multiple private networks out onto my public IP without natting everything? I'm setting up a cisco lab and want to be able to access it via the public internet remotely. My main problem is that I can't run a hardline to the lab location so I have to use wireless. The only gear I currently have for this is an old windows machine--I installed a NIC and a wireless card and activated routing and remote access. Everything is working except the cisco lab which is on a different private network can't reach the public. Everything that's being natted on the linksys gateway to the cable provider can get to the outside because it's being natted. How can I get the lab network out to the net without making it a part of the linksys' nat subnet? I had assumed since requests from the lab were being sent through the 2003 machine which is on the natted network, that those packets from the lab would also be natted but I don't think that's the case since it's originating from a different network. I have connectivity all through the internal network--just can't get the other network to the outside. I've attached a topology jpg so you can see everything that's configured. I appreciate any help you can provide. Thanks!!
