Yes, this happens when I connect from my machine (which functions as a router with NAT to allow the other LAN machines connect to the internet) to another LAN machine. When the router establishes a connection to another point in the intranet, the source address used is my official IP, and not 10.0.0.1, which is the intranet IP of the router. In other words, I want the source address to be 10.0.0.1 on every outgoing connection where the destination is inside my intranet.
