I'm no iptables expert (is anyone?), but these look like the lines of interest:
Code:
-A INPUT -p icmp -m icmp --icmp-type 8 -m limit --limit 1/sec -j ACCEPT
-A INPUT -p icmp -m icmp --icmp-type 8 -j DROP
If I interpret it correctly, any more than 1 icmp echo request packet per second will be dropped.

The following commands should remove these two lines temporarily until the next reboot or firewall reload:
Code:
iptables -D INPUT -p icmp -m icmp --icmp-type 8 -m limit --limit 1/sec -j ACCEPT
iptables -D INPUT -p icmp -m icmp --icmp-type 8 -j DROP
Just remember that someone put them there for a reason. You should find out where and how this was done so that you can make the change permanent if necessary.
