I am looking to install a seperate WAN for my client, for the purpose of failover. Firewall is a FortiGate 50B.
My question is, can I set up their current PTR for mail on the primary line, onto the second line also, so when failover occurs that part still matches?
My plan is to introduce the new WAN and:
1. Set the Static Route for the new line on a higher priority than the first
2. Copy all outbound/inbound firewall rules for WAN2
Then as far as I can see it's just the Mail side I need to do, i.e the PTR record.
