Hi, I'm using a debian woody box as my gateway at home, It has a network card for the local network (eth0) and a internal ADSL card for the internet connection (ppp0)
Everything was forking fine for the 2 years untill a few months ago someting happend.
The gateway still working fine and I can full access to the internet from any computer on the network, except fom it. I mean, if I log in to it (SSH2) I can't PING anything, on the local network or on the internet, even using the IP addreses.

xavier:~# route
Kernel IP routing table

default 62.241.161.247 0.0.0.0 UG 0 0 0 ppp0
Chain STATE (0 references)
target prot opt source destination
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
ACCEPT all -- anywhere anywhere state NEW
LD all -- anywhere anywhere

To have a closer look at the fancy settings it would nice with a listing from
