Xbox Live keeps disconnecting (Time Capsule)

[aukemid]

We got a new xbox 360 and every few minutes we get the connection lost message.
It's wired to a time capsule. UDP 88, 3074, 53, 80, TCP 3074, 53 and 80 are linked to the static ip from the xbox. These ports come from support.xbox.com.
I've made a dhcp reservation for the mac-adres to the ip.

Searching with Google I've found many threads about this problems, but none got really answered. Does someone has an idea what the problem might be and what might solve it?

(The xbox doesn't give any error messages and the tests always pass.)

I have the 2011 Time Capsule with those ports shared as well and I haven't run into any disconnecting. I'd remove this "I've made a dhcp reservation for the mac-adres to the ip" as you don't need it. If your Xbox 360 already has a static IP, the TC will only give it what you tell it to.

Many of my networking problems with xbox 360's got resolved by a full unplug. Try it you never know.

This is the best I could do...
Here's a simple guide to resolving the strict/moderate NAT problem for your Apple routers and Xbox Live:

If you want to try the DEFAULT HOST option(this is referred to as putting your Xbox in the DMZ; it puts the Xbox IN FRONT of the router, your internet connection bypasses the router and goes straight to the Xbox). This is the easiest/fastest method:http://www.youtube.com/watch?v=vcAtB5NUqKs

If you want to try NAT PORT MAPPING PROTOCOL- https://discussions.apple.com/docs/DOC-3414
here's the ports you'll need:
Port 88 (UDP)
Port 3074 (UDP and TCP)
Port 53 (UDP and TCP)
Port 80 (TCP)
