I have a couple:
1 If security is not a concern setup e-smith as server only, this way all traffic comes in and out of your LAN, downside is there is no firewall!
2 Run a dedicated quake server behind the e-smith, and connect to this (port fprwarding to main Q-server
after that - its beyond my expereince to offer any advice
Hope this is of some small help
