MessagePings are only allowed from the LAT to the Internet or from the LAT to the DMZ by default. You have to create packet filters to allow pings in any other direction. Keep in mind that you'll never ping from Internet (MZ?) to the LAT.

I do everything by the book (keeping the private addresses in the MZ segment in the LAT, enable IP routing and packet filtering etc.) If i follow the scenario of implementing a trihomed configuration as suggested by Tom Shinder, and enable the getting started article of the same author (allowing all access in both directions) I should be able to ping both from DMZ everywhere and from MZ also. This is not happening. Please assist me. ------------------------------------------------------------------------------ ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
