By default, the GWIA binds to all addresses when the server where it runs uses multiple IP addresses. Then each IP address is associated with all ports used by the agent.
To use an exclusive bind to one specific host name:
In the GroupWise Administration Console, browse to and click the GWIA.
Click Agent Settings and locate the Network Address section.
Select Bind Exclusively to Host Name.
Click Save, and then click Close to return to the main Administration Console window.
You can use the /ip startup switch in the GWIA startup file to establish an exclusive bind to the specified host name. If you have used this switch in the GWIA startup file, remove it to turn off the exclusive bind.
