I'm working on an old Mac PowerPC G5 that has two Ethernet jacks. I'm interested in finding a way to have both jacks setup so that all internal traffic (all traffic to and from a specific IP address range. E.g., 192.168.*) to be routed through one of the jacks, and the other jack to route all other traffic.
It sounds doable, but I'm not sure how to approach this situation. Any help would be much appreciated.
Thank you for the quick responses. I'm sorry for not being clear, I'm using OS X Tiger and I am not trying to share my internet connection.
My router provides two connections to my Mac (i.e., providing two internal IP address to my computer, e.g., jack #1 192.168.1.100 & jack #2 192.168.1.101)
Let's say I want to connect to a VPN on jack #2, but keep access to local resources on jack #1. (i.e, jack #1 192.168.1.100 & jack #2 VPN assigned 10.246.10.100)
In this example, I would want all internal traffic (to and from 192.168.*) to be routed through jack #1 and all other traffic routed through jack #2.
I hope this clears up my situation more.
