TNX Jakob. The modem is in bridge mode indeed and PPP assigment works 
but I would like to be able to use the web interface of the modem and 
more important, the modem sends syslog messages which I want to capture 
on miy server on the LAN. I seem to remember that I had this working 
when I tested with OpenWRT, a long time ago. But I want to stick to 
Monowall, though... I'm used to that and it serves me a well for a few 
years already.
