Okay, SOHO routers are cheap. I need to make sure that New Router #2 is 
resistant to ARP floods. Have you seen SOHO class routers that are so 
resistant? I can't justify buying big iron for this project.

Are you saying that using WiFi would compromise this one computer or that 
doing so would allow the dual-connected computer to bridge the two 
networks in an unprotected manner?
