Yah, the RT314 has both NAT and a hardware firewall (of sorts). And things have deteriorated. At first the rendercow specific system was seeing itself and my main machine; now it only finds itself. So I've gone from a one way ping to a no ping.... : On the other hand, Norton does have a few levels of 'disabled', so I might not have gotten it fully down.... I've got a bad feeling it is a routing issue, though. There are three comps on the LAN (mine, my wifes, and the rendercow box), and none of them can see each other. Cable access is fine. I wonder if maybe that built in switch isn't exactly a full duplex switch...? I =really= don't want to have to try and dig around in the router without a nice, thick manual to tell me when not to be stupid....
