Arno's firewall - blocking ICMP?

Hey all, I'm trying to block my computer from responding to ping requests.

I've found what appears to be the relevant syntax for iptables, but I can't use it with Arno' firewall script, which obviously is what I'm using for the rest of the firewall.

I've tried adding the iptables commands to /etc/firewall-custom-rules, with no luck

Does anyone else use this script, and have any ideas?

Thanks,
THom

# iptables -A INPUT -i $EXT_IF -p icmp --icmp-type echo-request -j DROP

Never used Arno's script, but that should drop icmp echo requests (pings).

Hmm nope that didn't work. Perhaps the custom rules are being overwritten or overuled by another rule or something.

Anyone actually used this script?
