Hi,

At home, I have a a network of 7 computers. All computers can (All running windows can connect to the laptop running Ubuntu, but Ubuntu machine cannot see the other computers on the network.

Has anyone ever experience this?
Everything was working, but then one fine day, it stopped.

I don't remember if I changed any settings, so if I did, is there a way to put things back to normal?

Also, the laptop is in DMZ on the router. (Directly exposed to the internet)
Could this be the problem?

Cheers - CC7
