Tried to disable MSN bits, but it still works?!

[xiphias]

Here's the issue. I'm home for christmas hols, along with my brother. This means theres probably a doubling in normal bandwidth needed. However, as me and my brother use webpages, no issue. The issue runs with my youngest brother, permanant resident of the household. Being a 14 year old, he's permanantly on the webcam all the time. Obviously this saturates the upstream bandwidth, and the net grinds to a halt. Being the selfish little ct he is, he won't listen.

Enough rambling. The obvious solution is to disable upnp on the router, thus killing msn's way of connecting. However, even with his pc behind NAT and ports forwarded, the webcam still works?

HOW?!!?

Take webcam.

Smash to bits.

Job done.

Yeah uPnP just facilitates the MSN's workings but it can work without them usually fine.

Some routers let you enable a sort of secure, web-only mode so only web browsing works. A bit mean but hey, if he won't listen.. . There should be an easier way to block the webcam though.

Not an expert, but I would think that you just need to find out what port the webcam is using and block it with the firewall.?

[malman]

If you have a firewall
block this lot

5004 - 65535 udp send and receive. To use audio/video features you have to open up a range within the one that is give here.

[xiphias]

I can't block ports, but theoritically I can forward them to a non-existent ip. I just don't understand how if it can't use upnp, and inbound packets will be blocked by nat, how it communicates?

[sp60]

If the connection is instigated from inside the NAT, there is no restriction on the ports that can be used.....unless there is a firewall setting blocking certain NAT connections AFAIK.

[agent006]

Yep, NAT only blocks ports that haven't been already opened from the inside. All the MSN traffic is initiated Client-side, so the inbound traffic is all responses.
