Secondary WAN IP address at the same interface

[James12]

To all experts,

I checking too see meraki MX is able to support the function of configure a secondary IP on the wan interfaces.
We have 1 static IP and 7 secondary ip address.
Cisco router is able to do so by 
int gi0/1
ip address 1.1.1.1 255.255.255.252 
ip address 3.3.3.1 255.255.255.248 secondary

I do see documentation on WAN IP configuration but could not find one documents on the secondary IP address configure.

not as a direct IP as far as I know, but you can do 1:1 or 1:Many NAT with different IP Addresses on the WAN Interface:

@Greenberet  thanks for the reply.
so on the 1:1 NAT I key my secondary IP address  ?

[Greenberet]

exactly, and then you specify the internal ip of the destination machine.

@Greenberet how about using secondary ip as public IP for certain traffic?
