hi
From: Mario Ohnewald [mailto:mario.ohnewald@gmx.de] Hello Sec-Experts! ;)
I have SuSE7.3 (uptodate) with 3 Interfaces. Everything runs smothly! But after some time, the Firewall-PC can not reach the Externam Network anymore, but the - ppp0 is up - ip is ok - DNS is correct - routing table fine
The Clients behind the Firewall can still ping and surf the web and everything! Look like the Firewall changes something oversudden. The logs look ok.
did you try to shut down the firewall and check the connection? didn't the external ip change after, like, 4 hours or so? how can internal clients ping the web when the firewall's lost its connection? can you post some of your firewall-logs for further analysis? perhaps there's a clue to see why your firewall-host has been cut of the internet. what does your syslog say?
[... snip ...]
Thanks a lot!
Mario
