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. I just have a bunch of these logs, where can i disable the logging of this entries (kinda different subject ;)?
