If you want to log every connection attempt: iptables -A INPUT -i ippp0 -p tcp --syn -m limit --limit 1/sec -j LOG \ --log-prefix "Connection attempted" This works for tcp connection only, though. Praise
iptables -A INPUT -i eth0 -p icmp --icmp-types \ destination-unreachable source-quench time-exceeded echo-reply \ parameter-problem -j ACCEPT
iptables -A INPUT -i eth0 -p icmp -j DENY
Sorry, I didn't see that it's an ISDN box. You will want to use ippp0 instead of eth0.
