Loving Meraki Client VPN For Remote Administration

My own love affair with Meraki started way earlier than Cisco’s acquisition of the cloud networking biggie. Though we use Meraki in targeted locations at my “day job”, I’ve followed their evolution in my long-running role as a gonzo freelance IT journalist since the days when they only offered Wi-Fi, then through the addition of the MX series of security appliances and Ethernet switches. I’ve had the rare frustration with Meraki’s features, but I do mean rare compared to the pain caused by other vendors consistent shitcode. For my own small consulting company, there’s one Meraki feature I’m incredibly fond of as an administrator- and that’s Client VPN. It’s easy to setup (but you still have to understand a few things), and incredibly empowering to the remote administrator.

Down on the Farm

My favorite customer is a prestigious large dairy farm that needed a network overhaul. When I took on the account, there was a mishmash of consumer-grade routers and switches in use, multiple 4G ISP connections, and lots of odd little islands of individual networks. I was able to tame the beast, making it a single decent network with point-to-point wireless bridges connecting far away buildings (using 5 GHz where possible, 900 MHz through trees), UPS, managed switches, and Meraki APs. Along with keeping the network healthy, I find myself doing a bit of desktop and device support. My philosophy is to never visit the site unless something new is physically being added. I’d much rather do everything remotely, which brings me back to Meraki’s client VPN.

Setting it up: the farm network is on the inside (part of what I inherited), with a single public ISP address on the outside of the Meraki MX. Here’s where you set up client VPN in the MX:

Then, you need to configure the VPN client on a PC, and here’s Meraki’s how-to. The guidance is straight forward, but I was first tripped up by a Windows 7 machine that absolutely wouldn’t work despite proper VPN settings (I’ve done a lot of VPN administration through the years, have never seen anything like this one odd Win 7 laptop).  Once you get the PC set up and connected to the MX with client VPN, you have to be mindful of what you’re doing between networks.

NOTE: My home network also happens to be just like the farm. This creates a routing problem going from my home network to the farm network over VPN, as I need to “come in” to the farm network from a differently numbered network (you’ll see why in a minute). I could solve this multiple ways- like by re-addressing my home network, adding a second VLAN/IP space to use for administering far-away networks, or tethering to my 4G phone that uses a different IP space on the “inside” when I’m at home). Just know that can’t client-VPN off to another site and then be used to administer the same IP space on the far end (not easily, at least). 

The last step in the process that allows me to reach into the private farm network with client VPN is to configure a static route that points my traffic to the farm’s network via my connected VPN interface (in this case The following shots show me 1.) connecting to the farm from a public network with VPN address, 2.) adding the static route in Windows and 3.) then both ping and trace route to farm network router at

If this seems complicated, it’s not. It takes minutes. From here, anywhere in the world, I can administer and monitor the devices on the farm as if I were standing there in the front office. Of course, PC configurations like Remote Desktop still need to be correct if that service is needed, but I’ve used the method described here to change printer settings, check on bridge links from the bridges themselves, and to find devices on the network that had been moved- all remotely and without travelling to customer sites. I know that this isn’t exactly cutting edge or exclusive to Meraki, but I haven’t seen a client VPN setup as easy as with the MX, myself. Well done, Meraki.
