How to open ATP 100 to ICPM pings.

I have a ZyXel ATP 100 between my cable modem and my network. On my network is a PBX phone system running on a Mac mini (FacetPhone). My phone vendor needs me to open my network to ICPM pings so they can diagnose a quality of service problem. I do not see any reference to ICPM in the manual. Can someone tell me how to do this (and then undo it when they are finished)? Thank you.

    You mean you want to allow ping from WAN to your internal server?

    What is network topology?
  • Thank you Sapphire23. Location 1: Internet connects to cable modem in bridge mode with fixed IP addresses. Cable modem goes to ATP100 which connects to network switch which connects to FacetPhone PBX server via NAT to local IP number. There are a couple other serves and desktop computers using Bria soft phone application for  telephone service over headsets.

    For ping to the ATP 100 you just need a Policy Control rule from WAN to ZyWALL with service ping.
