I said in the description that all of the computers on both LANs have static ips. My friends' computers are 192.168.1.99 *.101 *.102. And the computers on my network are 192.168.1.137 *.138 *.140. Both of us have the exact same ISP and service (through our cable company). I have a Linksys BEFSR11 router that connects to a switch, and my friend has the Linksys BEFSR41 w/ the built in switch. I don't think both of us use NAT, but I'm not familiar with what technology linksys is using in their routers... No computers on either LAN are setup as the DMZ host. Any more questions?
