Details about load balancing with
Network Prevent for Email
Servers in reflecting mode are as follows:- An MTA creates an SMTP connection to theNetwork Prevent for EmailServer VIP.
- The load balancer rewrites the destination address of each packet in each SMTP session as the IP address of one of theNetwork Prevent for EmailServers. The load balancer does not rewrite the source address.
- TheNetwork Prevent for EmailServer creates a connection directly to the originating MTA based on the unaltered source address of the incoming packet. The same holds for 4 and 5 in the diagram.
