Scenarios in which an event ID 9322 message may be logged in Exchange Server 5.5

The servers in a site communicate through a firewall that uses NAT

Consider the following scenario:

• Two servers that are running Exchange Server 5.5 SP4 are located in the same site.
• Server1 is in an internal network, 172.x.x.x. Server2 is in external network, 10.x.x.x. The external network is behind a firewall that uses Network Address Translation (NAT).
• NAT is used to translate 10.x.x.x into an internal IP address, 172.x.x.x.

In this scenario, mail may queue on the computer that is behind the firewall until the external server connects to deliver the messages. Additionally, an event ID 9322 message and an event ID 9318 message that includes error code 1722 are logged in the Application log.
