REMOTE DESKTOP FRUSTRATIONS

The problem is that two ports have to be opened in the modem which connects
to Optus. On these accounts an IP address is allocated dynamically at
login. So everytime you reboot the modem (once every couple of weeks on
average) you get a new IP address. The matter is further complicated by the
modem being attached to wireless LAN which allocates an internal IP address
to each attached device. I can open up the ports necessary on the modem but
they do not stay open after a reboot. Also with the firewalling in the
router, the opening of the ports through the modem gets blocked. I have
opened the same ports on the router but the IP address of the attached
devices is different from the IP addresses allocated by the modem. I have
to have a network bridge between the two which complicates matters by
another factor again. I think I need a combined wireless router/modem but
that would only overcome two of the problems? Does anyone know THE solution
to my problem? Please.
