I have enabled ping replies, but also added the following IPTABLES commands to DD-WRT's Firewall command area, disabling ping replies from all but the specified IP addresses:

iptables -A OUTPUT -p icmp --icmp-type echo-reply -d 127.0.0.1 -j ACCEPT
iptables -A OUTPUT -p icmp --icmp-type echo-reply -d 192.168.222.10 -j ACCEPT
iptables -A OUTPUT -p icmp --icmp-type echo-reply -d 74.208.229.54 -j ACCEPT
iptables -A OUTPUT -p icmp --icmp-type echo-reply -d 64.81.79.40 -j ACCEPT
iptables -A OUTPUT -p icmp --icmp-type echo-reply -d 64.81.79.41 -j ACCEPT
iptables -A OUTPUT -p icmp --icmp-type echo-reply -j DROP

The 2nd address is my local machine so I can ping the router, the 3rd-5th addresses are the IPs that DSLRP uses to test.

When I add another IP, and test from that remote machine, pings are replied to. When I remove that IP, pings are not replied to. So it works for all remote machines I have tested, but still I can't get the DSLRP monitors to work.

Any ideas?]]> http://www.dslreports.com/forum/SOLVED-DDWRT-Not-Pingable-27184318 Mon, 28 May 2012 13:06:25 EDT
