    My config. is as follows: DSL modem connected to a Linksys BEFSR81 Cable/DSL Router/Switch conected to a WRT54g connected to 2 pcs. I want to try an configure Remote Desktop but run into a small issue in trying to configure it. The BEFSR81 only allows me to forward to an ip containing 192.168.0._ . The ip of the WRT54G is It may also appear that the WRT54G pulls a dynamic ip of from the BEFSR81. So is my logic correct in assuming that the WRT54G pulls an ip from the BEFSR81 and that i do not need the router ip of If that is the case then is one of my options is to set up a static ip for the WRT54G within the BEFSR81 using its mac address? Or is there another way?

    All Help is Greatly Appreciated!

    Well you do not need one of your routers. Though if you want you can run both, you will have to forward RDP (port 3389) to the wan port ip of the wrt54g and then forward to the computer you are trying to RDP too. Static ip would be the best as you wont have to worry about the wrt's ip changing though its not necessary.

    I tried to explain above .... the BEFSR81 only allows me to input an ip addresss of 192.168.0._ and if the wan ip of the WRT54G is your solution will not work. So what next?

    The WAN port of the WRT is not, that is the IP of the WRT LAN. You correctly guessed that the WAN port is actually getting a 192.168.0.x address from the BEF. A much better configuration for you is to use the WRT as an access point only. The BEF is already your router, and using 2 routers (and double network address translation) has been known to cause problems.
    A very simple fix for your ills is to disable the DHCP server in the WRT, and connect the BEF into one of the LAN ports of the WRT, not the WAN port. The WAN port of the WRT remains un-connected to anyting. Then program your computers to use static IP (unless they are laptops that move between different networks). The static IPeez to use will be in the 192.168.0.x range of the BEF, but outside it's DHCP server range. Then in the BEF, forward port 3389 to the static IP of the computer you wish to log into.

    The other configuration that can be tried, in case you want to keep both routers is that on the Setup page of BEFSR81, change the local IP to and that will change the DHCP handout range to to 254 as well. For example,

    However, as explained in the previous port having one router as the Network Address Translator is sufficient. The other router can be used as an Access Point.
