I have PfSense Home server, with two interfaces, LAN and Wifi with Captive Portal.
DNS Resolver works perfectly for both, I forced redirection dns trafic at WAN Public DNS to the Firewall itself.
And Wifi Guests are only allowed
to :
DNS port 53 to destination 192.168.200.254
HTTP ans HTTPS for Web navigation.
My problem is : From Guests Wifi Network, my client can retrieve all LAN records (192.168.0.254 for example), with nslookup 192.168.200.254.
I would like to deny these Dns requests , I don't want my guests able to know my LAN ips/devices (Even if yes, other trafic is denied already).
