My router is set up as a gateway. I was using dhcp and am now set up as static ip's. After being connected to my internet (PPPoE) for about an hour (usually less), the router stops passing internet traffic and fails to respond to access requests to communicate to the router via it's http interface. It will still allow traffic between devices on the same segment though. I tried with dhcp and without, IPS on and off, firewall on and off. I tried different keep alive times. Nothing seems to work. Help.
