[Gllug] SuSE, firewall, BT broadband and IP

[Anders Odgaard]

I am trying to get the BT Voyager USB ADSL Modem to work on my SuSE 8.0
box. I have downloaded the eciadsl package from sourceforge
(eciadsl.sf.net) and have also studied the info supplied by Mark Adams
(http://www.thecaretaker.org.uk/drivers/btvoyager/btvoyagerlinux.htm).
The eciadsl information is very good and I have managed to connect to BT
broadband over ppp0.

The problem is that the connection is shut down whenever I try do use
the connection. The /var/log/messages contains the following lines when
shutting down the connection:

Dec 10 21:42:09 kontor kernel: SuSE-FW-DROP-DEFAULT IN=ppp0 OUT= MAC=
SRC=61.217.178.241 DST=217.43.14.244 LEN=78 TOS=0x00 PREC=0x00 TTL=112
ID=41601 PROTO=UDP SPT=1030 DPT=137 LEN=58
Dec 10 21:42:19 kontor kernel: SuSE-FW-DROP-DEFAULT IN=ppp0 OUT= MAC=
SRC=200.4.108.36 DST=217.43.14.244 LEN=78 TOS=0x00 PREC=0x00 TTL=101
ID=65186 PROTO=UDP SPT=1110 DPT=137 LEN=58
Dec 10 21:42:22 kontor pppd[10402]: Modem hangup

It would appear that the firewall aborts the connection. The firewall
configuration is - as far as I know - standard. I'm not allowing
services.

My local home network (over eth0) has hosts with IP addresses 127.0.0.1,
192.168.1.1 and 192.168.1.2. I have no idea why I used these addresses
when first setting up the home network.

Does anyone have a suggestion why the firewall shuts down the
connection? 
Do I have a conflict with my local network?
Has anyone successfully set connected to BT broadband using the Voyager
modem?

Thanks,
Anders
