Hi, I've been monitoring the NAT router with pktstat and am a little perturbed to see quite a lot of icmp echo requests. Now I've setup my Linux firewall to reject icmp echo requests. Is this the right(?)/correct/valid/appropriate thing to do? Furthermore (just for clarification) using tcpdump, I get incoming icmp echo requests, but no response from my firewall(good thing right?. This means the firewall is dropping/rejecting the echo requests? Here is the line from the firewall script: iptables -A INPUT -i eth0 -p icmp --icmp-type 8 \ -j REJECT --reject-with icmp-host-unreachable Btw, I'm quite bothered about the pings. It doesn't look right. --
