Guest wireless connecting but no internet

ARLamb200

Hi,

We have a couple of NWA1123ACv3 devices that are controlled through the Nebula portal. they have two SSIDs on them a business one and a Guest one, the business side is working okay, but the Guest one isn't. the users are connecting and getting an IP address but can't connect to the internet.

I have read a lot of the troubleshooting documentation about how to get this to work, but it hasn't fixed the issue.

The SSID is enabled and broadcasting (the users can see it)

We are using NAT mode, so shouldn't need our own DHCP or DNS Servers

Enable layer 2 isolation is greyed out, so I can't turn it on

The firewall is enabled and has the default entries in it

Can anyone suggest where I am going wrong please?
