seems quite strange, although the only thing i'd say, is make sure that the internet configuration is set to DHCP mode, and although it isn't required to open a port from a router, DHCP does require the use of port 67 and 68.<div>

run the modem to the primary PC to get an IP, then connect the modem<br>
to the router's WAN port, dive into the console and set the MAC<br>
address - which is as you say, the router clones the MAC address of<br>
the PC interface you're using and spoofs the modem into thinking it's<br>
still connected to that one PC. On an established working setup this<br>
shouldn't usually be necessary either, you should just be able to<br>
switch out the old router for the new and carry on as normal, but<br>
sometimes there's occasion to clone the MAC address.<br>

*some of the Surfboard modem hacks I've come across /do/ use port 68<br>
for console access, I'm not particularly keen on these as Port 68 is<br>
reserved for the bootstrap protocol client (RFC951) hence /shouldn't/<br>
be used for console applications especially for configuring modems!<br>
