I'm a new mac user and very impressed so far. One area I haven't been able to figure out yet, and hoping you all would be able to help. When I was using XP I was able to use 2 wired interfaces, each on a different network, and able to get both networks. However, on my mac if I have 2 interfaces up, only 1 can get traffic beyond the gateway. The 1 is whatever is specified first in the "Set Service Order".

I've tried link aggregation, but neither back end switch supports the protocol.

How would I set up my laptop to recognize where to send packets, or how do I make it a router?

Thanks for you help!
