Christophe, 

check my reponse to Aron just above this one. It explains a bit more as to 
whats going on.

In brief, if the firewall is turned off, then the inet connections become 
inoperable. When it is turned on things work. Thats a feature and "not" a 
bug. If this is a workstation behind an already configured firewall, then 
just allow everything. If not, then you'll have to configure some sort of 
rudamentary firewall. If you've got no services running other then maybe 
ssh to this machine, then when you turn the firewall on open the ports for 
the service you're running. Thats really all there is to it.

I would suggest reading up on IP Tables a bit so you've got some idea of 
whats going on as opposed to relying solely a GUI config wizard. If you can 
find the packages try installing Bastille on your system. Its probably the 
easiest out there to configure, and once its done you just let it alone.
