dns eror when i enable captive portal on pfsense (last stable realse)

hamedlynx

hi
i have configured pfsense completely
but when i activate captive portal on interface "switch" which is my local network
it won't redirect to captive portal page .
I got error which is DNS
i am running pdc-srv 2019 , my dhcp is runnig on my pdc-srv
in scope option i have defined dns servers : Like
192.168.14.10 which is my pdc-srv address
8.8.8.8 which is google
192.168.100.10 which is pfsense
and in dns server setting part on pfsense i have defined only 192.168.200.1 which is my router

i have 10 vlans which has diffrent range of ip address
like vlan 14 : 192.168.14.0/24
.
.
.
vlan 90 : 192.168.90.0/24
i create A record in dns on pdc "192.168.100.10 which is my pfsense lan ip address"
on the wan side i have router and i have configured dynamic dns like my ISP dns and google dns
clients in order to obtain ip address from dhcp i have configured " ip helper-add 192.168.14.10" in my switch core which is 3750x-12ss
and of course i have default route in my switch that routes all packets to 192.168.100.10(pfsense)
i have configured dhcp relay on pfsense , i thought it was the problem , sadly it wasn't
any ideas ??? tnx
:-(

Noop.
To many 'things'

Make about : make a LAN 192.168.1.1/24 as a LAN.
Another LAN called ... OPT1 ;) using 192.168.2.1/24
On OPT1, put a firewall pass all rule.
Add a DHCP server on OPT2 with a pool.

No DHCP relay, no 'router', no VLANs, nothing.

When that works, add 'one' thing, and test severally.
It works ? Add something else. And test.

Something breaks ? you know what is was.

When you're wired up with the portal, over wire or Wifi, DNS should work.
The only DNS that gets passed, is not 8.8.8.8 - as everything is blocked.
The DNS that works is : the portal interface, port 53. So the connected user should use that one, and not some 8.8.8.8.

Then a http:// (not https://...) request should be possible .... etc.
