Hi again,

OK, brought some logs in.

When my internet connection stopped on Saturday. At this point eth0
still reports having an IP address in the weblet --> Network Setup
I tried running the pump command, this is the DHCP client, yes?. It
wrote this to the log

Mar 1 11:45:32 firewall kernel: eth0: Setting Rx mode to 0 addresses. 
Mar 1 11:45:32 firewall kernel: eth0: Setting Rx mode to 1 addresses.

Mar 1 11:45:32 firewall pumpd[27199]: breq: vendor: 0xff

Once I do that, ip addr shows that eth0 has no IP address. Internet
access is still down.

Apart from that, the only things in the log is lots of this...

Mar 1 07:15:01 firewall /USR/SBIN/CRON[16448]: (root) MAIL (mailed 12
bytes of output but got status 0x0001 )
Mar 1 11:45:01 firewall /USR/SBIN/CRON[2897]: (root) CMD
(/etc/multicron-p)

Lots of blocked packets, the last of them being this (x3)

Mar 1 09:12:23 firewall kernel: Shorewall:net2all:DROP:IN=eth0 OUT=
MAC=00:20:af:e1:2d:00:00:05:5f:ee:b0:a8:08:00 SRC=212.241.103.151
DST=81.102.124.19 LEN=48 TOS=0x00 PREC=0x00 TTL=117 ID=1612 DF PROTO=TCP
SPT=1172 DPT=139 WINDOW=16384 RES=0x00 SYN URGP=0

I have the rest of the log if anything else is needed...

I read the rest of the shorewall FAQ, but I can't see the problem. The
only thing I can think of is that it's the cable company, but because
I'm not using windows they won't give me any support.

I do have sources of information about their network though.

OK, that's it. Thanks!

James
