Captive portal from VLAN to access LAN

Panagiotis Vakerlis

Hello everyone,

I've just started playing with VLANS and successfully set one up for guest users. I have 2 rules for this guest network, 1 GUEST -> WAN without restrictions and 1 GUEST -> LAN with captive portal and show captive portal for unauthenticated users.

Problem is, from the guest network when I try to access a web page on LAN I don't get the captive portal page. If I go manually to https://x.x.x.x:8090 (x.x.x.x is the internal XG ip, 8090 is the captive portal port) it will show the captive portal and when I log on I have full access.

Any ideas?

    Sorry about that, should elaborated more. Captive portal is enabled on the newly created zone with all the tickboxes. DNS does not apply since I have the filtering on LAN, not WAN. Nevetheless I created a test fw rule to forward DNS to no avail. 

    Just to note if this helps: I have let's encrypt ssl on the XG for the hostname it uses (Meaning if I go to https://mydnsname.com:4444 my connection is secure. Don't know if this screws up things on the inside

    On Log Viewer, I can see the Guest address trying to reach a LAN address and get rejected with the firewall rule I've created

    Hm strange thing. Went to Captive Portal settings, changed login prompt to custom message, included the link to direct captive portal ( in a form of <a href=https://x.x.x.x:8090> Click To Authenticate</a>). The IP used is the XG gateway of the Guest network.

    Now I get the page from captive portal saying that I can't login because I'm not authenticated. Good thing is since I included the captive portal link, I can click that and then I get to the proper user portal and login.

    A bit dirty but until we can find a solution it works!

    Strange thing that on the login method "Include link to the captive portal in the user notification message", I get a timeout trying to load the page. But on the moment I switched to "Display a custom message" it worked.
