[SOLVED] Cannot ping the local domains?

[shamsat]

I have debian wheezy with resolvconf, dnsmasq and apache2 running web server for my local domains, i have dynamic ip so the script updates the "/etc/hosts" on each
new dialup connection for the new ip.
The problem is i can ping the global net and the local domain with the ip 127.0.0.1 like one from /etc/hosts "me.example.net"
but cannot ping the local domains with the ip address 192.168.1.1 like domains from the /etc/hosts.dnsmasq:

ping example.dynet.com
PING example.dynet.com (192.168.1.1) 56(84) bytes of data.

You need to edit your firewall rules (iptables and/or ip6tabes) to allow icmp packets. Also, you may need to turn off a flag in /proc/sys/net/ipv4/icmp_echo_ignore_all with the command "echo 0 >/proc/sys/net/ipv4/icmp_echo_ignore_all" (as root or sudo).

If that doesn't work, then your router may be blocking icmp packets and replies, in which case you will need to alter that to all local pinging of your hosts/servers. You still want to block pings from outside your network as that is a common source of denial-of-service attack.
