What type of VIP should I use?

[jfpamesa]

Good Day,

I will be creating an email server which will be placed in our DMZ. Now, I will need to add a VIP so I could make use of 1:1 NAT but I am confused with the VIP types. I've read this documentation about VIPhttps://doc.pfsense.org/index.php/What_are_Virtual_IP_Addresses but I'm still confused. Someone please give me an idea on what's the best VIP type to use in this kind of situation.

Thank You! ;D
