By default, the Internet Agent sends outgoing messages on the primary IP address of the node 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 where the Internet Agent could fail over.
If the Internet Agent has a large number of nodes available, you could configure the Internet Agent
to send outgoing messages to a relay host, which then sends them out through the firewall using its
own IP address rather than the IP address of the particular node where the Internet Agent was
running. This reduces the amount of modification to your firewall required to set up the Internet
Agent. However, if the relay host goes down, outgoing messages are delayed.
As another alternative, you can configure the Internet Agent to use its secondary IP address for
sending as well as receiving messages. Setup instructions for this configuration are provided in
"Forcing Use of the Internet Agent Secondary IP Address" on page
after installing the Internet Agent software.
In preparation for installing the Internet Agent, configure your firewall as needed to handle the
Internet Agent's use of primary and secondary IP addresses when sending and receiving messages.

involved in planning to install the Internet Agent are the same in a clustering environment as for any
other environment. Review the installation instructions in
