I thought Cisco had changed it so the user agent wasn't the only thing
it looked at to identify your system.  As a side note, I would
configure your router as a switch instead so the computers behind your
router still get 10.x.x.x rather than 192.168.x.x addresses.  With
that method, I believe you don't need to do any port forwarding.  I
think you just set DHCP passthrough, give your router a DHCP or static
IP on the subnet, and turn off the DHCP service on the router.
