[NEBULA] Captive portal authentication when the internet is down on site

ocsinghjr

I have a inquiry regarding Nebula AP? What will be the behavior if captive portal is enabled and but the internet went down? How can the Nebula AP authenticate the users while the internet is down?

Hi @ocsinghjr,

When doing captive portal, the client will query http website and gets the IP of http site from DNS server. 

Usually, the GW, DNS server and menagement VLAN of AP should be able to connect Internet to let Nebula AP online NCC, so should be no problem of captive portal authentication. If the Internet went down, the captive portal landing page might not pop-up.

Thanks.
