Captive Portal no longer working 2.2.6

[kapara]

I have captive Portal configured on a vlan.

Interface: 192.168.22.1/24

DHCP entries specified:

192.168.22.100-199

Gateway: 192.168.22.1
DNS: 192.168.22.1

All devices connect, recieve IP.  Sometimes I can run ping on iphone and sometimes not.  It is random.

I have rebuilt firewall 3 times now with no success.

If I put the old unit back running 2.1 it has no problems with displaying the captive portal page so I dont think it is the switch!

I even added 1 to net.inet.ip.fastforwarding in the system tuneables

I have another vlan that is using WPA Enterprise and that is working and passing traffic.

Now additional issues.

So I can ping IP on wan but DNS resolution is not working.

I have 4.2.2.2 and 8.8.8.8 in General>DNS for WAN interface.

Hi !

You use the default built-in html portal age ?
If not, do so, and case solved ;)
(look carefully at Services => CaptivePortal=> ZONE => Configuration, the example html page )

So it looks like for some reason Google DNS is not working from this location at all.  I disabled DNS resolver and enabled DNS Forwarder and changed DNS under general to Comcast instead of google and all working.  :o
