Problems redirect to web autenthication WLC 2504

[Jefferson Madriz]

We have a WLC 2504, since a few months, it was working fine, we have a guest Wlan configure with web authentication and the DHCP scope for this in the WLC. The problem today is that its no redirecting the web browser to 1.1.1.1, we try it with 3 laptops and they recieve a correct IP from the DHCP but still can not get redirect to the web authentication portal. Have the default configuration Internal (Default).

In laptops we check the firewall, dont have a proxy activate and have google DNS.. 4.2.2.2 8.8.8.8. In fact this laptops connected to this ssid before.

Typically when you get an ip address but not a splash page, its a dns issue.  I would take a laptop and connect it on the same vlan that wireless guest users or the vlan that your having issues and see if you can access the Internet.  If you type in https://1.1.1.1 in your URL, and you get the splash page, then everything is fine but leads to a DNS issue.  I'm also guessing your nto using a 3rd party certificate since your DNS is public.

Thanks,

Scott
