What exactly do the Internet Port and Public IP settings mean on the CISCO Meraki Z1 gateway?


Note: this is a detailed explanation with images - I apologize for its length but I'm striving for quality.


I'm setting up the Z1 for my father to connect to a VPN with a cloud-hosted service from his work. It seems like the configuration should be easy, but I'm getting some grief from the tech people at the cloud hosting service but not really getting their help in figuring out the answers.

Network config:

Internet <--> DSL Modem-Router <--> Meraki Z1, Wireless Router, etc.


The specific problem I'm having is that I've been told that the Internet Port and the Public IP settings for the Z1 should be the same. I don't think I can set up the Internet Port to match our public IP since that would mean that the actual endpoint on the Internet would be the Z1 - and that's not possible since we need the modem.

My solution so far:

I checked and followed the Meraki Z1 installation documentation:

Instructions from CISCO configuration website

It tells me that the only necessary WAN configuration for the device is to tell it how to connect to the Internet, which it can do through DHCP or statically (I've set it statically to be sure it's the correct way to do it).

I've also set the public IP address on the configuration page, so that it knows our IP on the Internet.

The current overview on the device looks like this (all green):

This looks like it's ready to go. So, in summary: have I made an incorrect assumption? Should I do something differently?

Thanks a lot!

I think you're understanding the configuration correctly! The Internet Port IP address is the address of the physical port. If your ISP router/modem is in pass-thru mode, then the Public IP address will be the same as the Internet Port IP address. But, since your Internet port IP address is a private IP address, the Public IP address will reflect the public address assigned by your ISP as detected by the Meraki Cloud Controller.

  • This is great. I actually had to get my ISP to set up my router/modem to pass-thru in order for the manager of the Meraki to be able to get to it. Thanks! Mar 10, 2015 at 17:28

Meraki devices should be configured and managed remotely by a controller located in the cloud Meraki Dashboard Login. Locally you have access to limited information like the connectivity info.

If your modem provide Internet access on LAN and gives private address through DHCP, you should not configure a public IP.

If you don't own a meraki dashboard account and the device is not attached to your account, you will not be able to manage the device.
