hi! 3 days ago I've written an email to you. thanks for your help! everything worked fine, except the nfs. I opened the ports 2049 and 111 completely, but I still get this error message: mount: RPC: Wartezeit abgelaufen ("waiting time expired") I tried to log everything blocked by the firewall, but it didn't work. I don't find the log file of iptables nor in /var/log/messages. These things I've already tried: 1) iptables -N no-conns-from-eth0 iptables -A no-conns-from-eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A no-conns-from-eth0 -m state --state NEW -i ! eth0 -j ACCEPT iptables -A no-conns-from-eth0 -i $DEV_EXT -m limit -j LOG --log-prefix "Bad packet from eth0:" iptables -A no-conns-from-eth0 -i ! $DEV_EXT -m limit -j LOG --log-prefix "Bad packet not from eth0:" iptables -A no-conns-from-eth0 -j DROP iptables -A INPUT -j no-conns-from-eth0 iptables -A FORWARD -j no-conns-from-eth0 2) iptables -N my_drop iptables -A my_drop -p ICMP -j LOG --log-prefix "DROP-ICMP " iptables -A my_drop -p UDP -j LOG --log-prefix "DROP-UDP " iptables -A my_drop -p TCP -j LOG --log-prefix "DROP-TCP " iptables -A my_drop -j DROP 3) iptables -A INPUT -i $DEV_EXT -f -j LOG --log-prefix "IPTABLES FRAGMENTS:" iptables -A INPUT -i $DEV_EXT -f -j DROP 4) iptables -N logdrop iptables -A logdrop -j LOG iptables -A logdrop -j DROP iptables -j logdrop can anybody tell me where I can find the log files? answers in german would be very helpful, but many thanks to all!!!
