NAT on WAN1 interface and No NAT on WAN2 interface

I have two internet service providers. On WAN1 i would like to enable NAT. On WAN 2 I would like to it to be on pass through mode.

 

How do i achieve this?

After letting Meraki-support enable the NAT-exemption feature, you can selectively disable NAT per WAN-port and even per VLAN.

Works good. With one customer I habe a direct internet-line on WAN2 with NAT, but on WAN1 the ADSL-router in front of the MX is doing NAT, so I disabled NAT on that port.

 

You probably don't want to have the "Meraki Passthrough" mode which would work as a L2 bridge on a single WAN and routed mode on the other? That is not supported.

As @Karl mentioned, you will need Meraki support to assist in enabling the No-NAT feature.

You can then change this per uplink or per VLAN.
