Trying to change the netmask to 255.255.0.0. Is this possible? I see theres static and dynmaic routing tables that can be setup but I dunno if those would be useful for my situation. I'm using a Speedstream 5100b modem and the PPPoE and DHCP from the modem, just want the nat'ing and other abilities from the router. I know the 5100b can do NAT but it doesn't do port forwarding and that.
