I can't seem to get my ISP's IP address assigned to my nic that is extenal to the network unless I create a rule with DHCP protocol and giving external traffic accesss to that protocol. I have my ISP's DHCP server address but it will not work with that IP address as sorce. I'm using Cable for internet access so my IP's are Dynamic. When the lease expires, the connection goes dead if don't have this rule in place. Is there a different way to get IP's assigned from my ISP to my external nic without giving the whole world a peek..
