Meraki is Cisco's cloud managed networking solution.
|
|
|
|
It has everything and more than what most people would need.
|
|
|
|
But of course me being me, I don't like my infrastructure being managed by cloud services.
|
|
|
|
|
|
|
|
I did however work a little with Meraki at SkyLabs, and was pleasantly surprised.
|
|
|
|
After having a couple very bad experiences with our Mikrotik setup script.
|
|
|
|
Setting up a Meraki access point with our captive portal service was super easy!
|
|
|
|
|
|
|
|
## Captive portal setup
|
|
|
|
As mentioned the captive portal setup on Meraki is relatively simple.
|
|
|
|
And with a little luck the only 100% necessary configuration options would be just a "splash page URL" and RADIUS.
|
|
|
|
And if the captive portal ain't responsible for authenticating people you could probably get away with just the splash page URL.
|
|
|
|
But RADIUS is needed for actual captive portal authentication.
|
|
|
|
|
|
|
|
### Access control
|
|
|
|
Even having a captive portal setup makes it incompatible with certain other options.
|
|
|
|
And I think Meraki is a bit excessive with the limitations here.
|
|
|
|
|
|
|
|
##### Network access
|
|
|
|
For the "Network access" you'd likely want it to be "Open", but if not.
|
|
|
|
PSK, aka normal password is your only option for adding additional auth requirements.
|
|
|
|
|
|
|
|
##### Splash page
|
|
|
|
Set security to; Sign-on with "my RADIUS server".
|
|
|
|
|
|
|
|
###### Advanced splash
|
|
|
|
In here there are a few options you may want to change that changes the behavior of the captive portal hot-spot.
|
|
|
|
Such as limiting users to being logged in with one device only.
|
|
|
|
If users are allowed through if the box/access point can't connect to Meraki Cloud.
|
|
|
|
The "Captive portal strength", this lets you allow non-HTTP traffic before captive portal login.
|
|
|
|
And last, but definitely not least.
|
|
|
|
The Walled garden, walled garden lets you have a list of allowed IPs that may be connected to before authorization.
|
|
|
|
|
|
|
|
##### RADIUS
|
|
|
|
For RADIUS you'll need the IP and RADIUS secret for the server.
|
|
|
|
Default RADIUS ports are 1812 for authentication and 1813 for RADIUS accounting.
|
|
|
|
|
|
|
|
### Other options
|
|
|
|
There is also a separate Meraki dashboard page specific for "Splash page" options.
|
|
|
|
In there you'd put your "Custom splash URL", although you may also manage a Meraki provided captive portal there.
|
|
|
|
|
|
|
|
## Caveats
|
|
|
|
One thing that's kinda annoying about Meraki however is its RADIUS client.
|
|
|
|
Meraki uses cloud based RADIUS clients, so from our side, we can only differentiate between them by the data that's sent.
|
|
|
|
This has caused us to add some extra limitations on Meraki setups using our captive portals.
|
|
|
|
Ain't too bad, but for RADIUS accounting to work it kinda gets ugly.
|
|
|
|
And we would need RADIUS accounting for our paid SMS login.
