4.1.4 Planning a Secondary IP Address and Cluster-Unique
Port Numbers for the Internet Agent and Its MTA
As with the MTA and the POA, the Internet Agent needs a secondary IP address and cluster-unique
port numbers. As part of planning to install the MTA and POA, you should already have determined
the secondary IP address and cluster-unique port numbers for the Internet Agent and its MTA as you
filled out the
“IP Address Worksheet” on page 40 . If you do not have a filled-out copy of this
worksheet for your system, print it now and fill in current system information.
4.1.5 Preparing Your Firewall for the Internet Agent
The Internet Agent receives incoming messages on the secondary IP address of the Internet Agent
domain volume. Your firewall configuration must be modified to allow inbound TCP/IP traffic from
the Internet to the Internet Agent secondary IP address on the following standard ports:
Table 4-1
Standard Ports
By default, the Internet Agent sends outgoing messages on the primary IP address of the server
where it is running . If you decide to use this default configuration, your firewall must be configured
to allow outbound TCP/IP traffic from all nodes in the Internet Agent volume failover path.
INTERNET AGENT CLUSTERING WORKSHEET
Under Item 3: Internet Agent Failover Path , list the nodes that you want to have in the Internet Agent
volume failover path.
INTERNET AGENT CLUSTERING WORKSHEET
Under Item 5: MTA Network Information , transfer the MTA secondary IP address and cluster-unique
port numbers from the Internet Agent section of the IP Address Worksheet to the Internet Agent
Clustering Worksheet.
Under Item 1: Shared Volume for Internet Agent , copy the MTA secondary IP address under Cluster
Volume IP Address as well, because they are the same.
Under Item 7: Internet Agent Network Information , transfer the Internet Agent secondary IP address
(the same as for its MTA) and the cluster-unique Internet Agent port number from the Internet Agent
section of the IP Address Worksheet to the Internet Agent Clustering Worksheet.
