I've got a new Draytek 3300v and I've been running it for a few days.

I've noticed when looking at the Data Flow Monitor that my machine consistently has 200+ sessions when other, more heavier users are much lower around 30-40.

The only difference is that my machine is Vista and the others are XP.

Visiting the NAT Session table I can see ALOT of sessions with expiration times of 7+ days.

What is causing this? How can I stop this? Any ideas? Is it Vista that is causing this? I thought Nat Expiration is set by the router? Can we set MAXIMUM timeouts?
