We have 4 appliances in cluster.
1 is Master (No Scanning)
1 is Failover (No Scanning)
2 are scanners.
We have assigned 1 physical IP (10.10.1.108) and 1 Virtual IP (10.10.1.109) on Master and
on Failover we have 1 physical IP (10.10.1.110) and 1 Virtual IP (10.10.1.109)
on the other hand on scanners we have 1 physical IP each (10.10.1.111 and 10.10.1.112) respectively.
My doubt is in sending and receiving emails.
can i use the same VIP (10.10.1.109) to send and receive traffic. or do i need to add of make any changes. please suggest.
The VIP should be used to receive emails. When sending the IP address of the appliance actually sending the message wil be the source of the connection.
If you require additional customisation of the inbound and outbound IP addresses you can look at the option of configuring virtual hosts.
Hope this helps.
