I have a design question regarding a port forward and a multi-wan set-up using Meraki MX. Lets say I have an MX with a triple WAN set-up.
Below shows the proposed idea.
With port forwarding, It looks like I may only be able to configure dual WAN port forwarding, see the below example:
My confusion lies within the complexity of the port forwarding. With the two devices above is this even possible when configuring the port forwarding onto the MX?
It seems pretty straight-forward for two WANs, but since WAN 2 port on the MX will connect to the CP E300 router, it will actually be given a private IP, the E300 router will be the gateway which then connects to the WAN 2 + Cellular.
In this scenario, how can I ensure the port forwarding works regardless of whether we have failed over from WAN 1 onto WAN 2 or LTE?
