Problems with NAT...Need assistance.

    I have a router that connects to my cable modem, but I want to disable NAT on one of them, so that double NATTING won't occur.

    I tried disabling NAT on the broadband router and used a static IP to connect to the cable modem, but I wasn't able to connect to the internet. Then I tried to bridge the cable modem and use automatic-DHCP on the broadband router to host the internet connection, but every once in a while my internet connection would go down and rebooting everything didn't work. Then I tried putting a static Public WAN and gateway address for the broadband router, but that only kept my internet connection up for a few days until it started dropping again.

    Is there something wrong I'm doing? Any reason for the internet connection going out?

    im assuming your cable modem has a built in router otherwise theres no "double natting" happening? Just plug in from cable modem to one of the switched ports instead of the WAN port, disable dhcp and let the cable modem give IP addresses to the whole single subnet

    I keep forgetting about the switch ports of these linksys routers compared to cisco routers as they don't have built-in switches.
