[arm-allstar] Suggestion for firewall script addtion

[Stephen - K1LNX]

Hi guys,
    Would like to make a suggestion for the firewall script located at
/etc/openvpn/firewall. I like to enable ping to determine if the host is
alive, so I added the following line:

### Allow ICMP traffic from internet
$IPTABLES -A INPUT -p ICMP --icmp-type 8 -j ACCEPT

Does this file get overwritten at all with new releases? That was my
concern and why I am making the suggestion.

tnx and 73,
Stephen
