Help, Loosing Port forwarding

[exect]

I keep loosing my port forwarding on a regular basis and wondered if anyone has any ideas?
I use a Netgear DG834G and have tried replacing it.

My IP address is fixed and the updater says its up to date, and the only way to get normality is to reboot the router.

My ISP says they are not the problem.

Hi
For anyone else that has the problem, it turns out to be a conflict between the PC and Router Firewalls.
