    hi..i tried to test my security using www.grc.com shield UP!! and i got a failed message as:

    Ping Reply: RECEIVED (FAILED) — Your system REPLIED to our Ping (ICMP Echo) requests, making it visible on the Internet. Most personal firewalls can be configured to block, drop, and ignore such ping requests in order to better hide systems from hackers. This is highly recommended since "Ping" is among the oldest and most common methods used to locate systems prior to further exploitation.

    is there something i should concern? or is there any rule i need to create?

    thanks for the help...:)

    Hi agustan.
    You need to sort out your ICMP rules,you should allow:-
    Outbound - types 8 (echo request) and 3 (destination unreachable)
    Inbound - types 0 (echo reply),3 (destination unreachable) and 11 (time exceeded).
    If you need to be pinged for whatever reason,you should allow:-
    Inbound - type 8 (echo request)
    Outbound - type 0 (echo reply)
    If you can,have the last two rules setup in your firewall,but disable them,then when needed (not very often,if ever)then you can just enable them.

    Hope that helps
