• A Pool containing the Exchange 2010 Hub Transport servers;
• A VIP for the SMTP service with a listener on the public network.

To create a new Service Monitor select the Local Traffic and click the + symbol next to monitors. Give the new monitor a name like SMTP_Monitor and if needed adjust the service health monitoring interval. Continue reading SMTP load balancing with F5 LTM →
