We have one FW with a localnet and a DMZ behind the FW with Exchange server
sitting in the DMZ. I have set up the Directory Service and Information
Store used by Exchange and Outlook clients to use two specific high numbered
ports called DirStore and InfStore.. Everything appears to be working okay,
but the log is filling up with the following entries that are being blocked
by rule 0. With Valid IP meaning the Valid IP assigned to the NIC on the
external interface of the FW and Random Ports are just that - the ports vary
between each log entry.
Origin Service Source Destination
Proto Rule S_Port
Valid IP random ports Exchange Srv
Valid Ip tcp 0
Exchange_InfStore
Valid IP Exchange_DirSer Local PC Exchange Srv
tcp 0 random ports
Again, all appears to be working okay, but the log will fill up in minutes.
Any insight would be appreciated.
