Ping error

[Peter Silva]

very likely you have put unintended firewall rules in place.
To eliminate all firewall rules and reset, you could do the following in a
root shell:

iptables -P INPUT ACCEPT
iptables -F INPUT
iptables -P OUTPUT ACCEPT
iptables -F OUTPUT
iptables -P FORWARD ACCEPT

Then try the ping.  If it works, the problem has something to do with the
firewall setup.
