Cisco 801 - Idle timeout

    Hey guys,

    I recently bought a Cisco 801 router for use with ISDN. Everything is configured so far, but I've got two questions. Firstly, the idle-timeout in the config below is set to 60 seconds (dialer idle-timeout 60). This doesn't seem to work, as yanking the Ethernet cable out for over 2 minutes elicits no disconnect. Strangely, however, with the cable in and the computer on, it does disconnect after 2 minutes of inactivity. How can I get the router to properly disconnect upon no LAN activity for 2 minutes like I want it to?

    Secondly, if someone could give me a brief synopsis of the kind of access list I need to forward a particular port or range of ports to a particular IP, since my network has all static IP addresses.

    Any replies would be greatly appreciated.
