I'm uncertain why you'd get that response, but i'm assuming from your regular ip changes that your situation precludes setting a static ip address, it might be worth you nipping into the help chatroom WinMXWorld.com Help_A06F7657BABE & asking someone about the 3.1 beta patch, while this beta series is no longer under development, the particular patch will configure most routers via uPnP & could save you lots of hassle with amending forwarding rules.
