-> Absolutely confirmed here.  Cable Modem goes next to a SWITCH.  From there t 
-> goes line to line to other hard switches OR to OTHER ROUTERS.  The WRT54G is 
-> one of such behind the cable modem via switch that handles it all back and 
-> forth to the cable IP provider. 
  
I have an odd setup there.  Business gateway with a Cisco 1U router 
hooked to one port that controls the BBS network and then the SonicWall 
Pro 2040 firewall which controls everything else that isn't on a public 
IP address (the SonicWall itself takes up one public IP).
