Incorrect redirect for guest portal

brian_hoyt_6612

I have a ZD1100 with 9.8.373 (I have R700) that I am having a guest portal issue with. When I connect to guest WLAN I do not get redirected properly to portal page on controller. If I type it in manually it works however. I have done packet captures on Wi-Fi interface of client and it appears the client is being redirected to wrong IP. Controller is .241 but the client gets .10 instead or gets the wrong DNS name. Is there somewhere in controller to configure DNS name rather than IP that it might be giving out improperly? Right now it just recursively gives out wrong redirect until it fails.

I have opened case with support but I thought I would see if others had any ideas.

Hello there!

Greetings from Mexico,

I had the same problem, but the issue its not with the controller itself, its the version.

I deployed in 3 different proyects using captive portal, but to work properly it's using the version "9.6.2.0 build 13" or any version "9.6."

regardless of controller you have.

I have to run 9.8 unfortunately though since I have R700 which are only supported with 9.8 and newer.

Were you getting redirected to incorrect page as well?

My problem was using a SAN cert it appears and the first DNS name in cert was used instead of correct FQDN. I removed / reset cert and the problem disappeared.

i have this / similar problem its going to controller 1s dns name even when it has failed over to controller 2. i used a wildcard certificate - i don't really want to buy 2 certificates just for guest portal...

Wow, just found my old post on this. It seems this is still a problem in 10.1.1.0 build 26 any ideas?

brian_hoyt_6612

Well I re-keyed my SAN cert to have our WiFi DNS as first one and it works. Luckily this is only one with the issue.

Running into the same issue in v10.1.2.0.120. I will be re-uploading the cert tonight during a maintenance window to see if that solves the problem. I don't understand why the entire ZD needs to be rebooted after a certificate is imported.

When guests are sent to the captive portal, their browsers are being redirected to the hostname for a different controller. This is probably the result of us shifting configurations around after we had a ZD fail. The configuration for ZD #5 was restored onto the hardware of what was traditionally ZD #1. Now ZD #5's captive portal is trying to send users to the URL for ZD #1.

EDIT: Confirmed that re-installing the certificate fixed the issue
