Alias IP Addresses

Establishing additional IP addresses for a network interface can be useful when changing network numbers and you want to accept packets addressed to the old interface.

If the address is on the same subnet as the first network address for this interface, a non-conflicting netmask must be given - usually, /32 (255.255.255.255) is most appropriate. All configured additional IP addresses will respond on the configured SMTP port as well as the configure UI port.
