I have a Linksys WRT160N Wireless Router/Access Point that I am trying to use behind a Watchguard Firebox firewall. The Watchguard Firebox acts as a DHCP server handing out addresses to a network for hardwired network items such as a network printer, desktop PC and a NAS device and is set to give addresses of xx.xx.xx.100 and below. I want to have the WRT160N to act as a DHCP on the same network for my wireless laptop and limit it to handing out addresses beginning at xx.xx.xx.190. The problem I am having is that when I assign the WRT160's device IP address to the same network (i.e. xx.xx.xx.160) and try to have it act as a DHCP server, it will assign an IP to the wireless laptop OK, but within a few seconds, I lose all connectivity to the internet on the wireless laptop. The WRT160 works fine as a DHCP server as long as I leave it on a seperate netork (i.e default of 192.168.1.1 or any other) and the problem only occurs when I try to make it work on the same network as the other devices. The WRT160N is a version 2 with firmware version 3.04. Any ideas?
