my centos is conect to a cisco router. I've got a leased line to my ISP connected trough cisco router point-to-point. and I got some routeble IP's in my network including this server which is the gateway in the internal network and in it's time the external gateway is the router connected to the ISP.
with iptables -L -n command I got
Chain icmp_packets (1 references)
target prot opt source destination
ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 8
ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 11
