16.7 Legacy Series / Re: Captive Portal not working with Android devices
« on: September 28, 2016, 04:53:07 pm »
Problem solved!!! But I don't understand why...
During the very first installation of the system (16 months ago) I defined a list of DNS servers under "System/Settings/General".
And the first entry was our local domain's DNS server.
The one that is used by all domain members.
The public DNS servers follow after that internal one.
Maybe this is not a clever configuration but it always worked.
Removing our internal DNS server from the list lets Android clients log into Captive Portal.
I do understand that a WIFI client cannot access that internal DNS server as this is blocked by the firewall.
But:
- Why is no other public DNS server used?
- Why did it work for iOS and Windows clients?
One other thing: I just installed 16.7.5 over 16.7.4. Any possible influence?
Best regards
