i tried the preferred method but its not working. I have a pfsense router on 2.3.2-RELEASE-p1
i am still having issues
I don't know that anyone on the team has the same hardware to replicate any issues. How are you setting the DNS?
setting the DNS under DNS Server Settings
You should be setting the DNS server under DHCP Setting as these are the settings that your clients will get. Could you also provide some more information as your OP was a bit vague.
There may be a conflict, If i remember correctly, pfsense also uses dnsmasq. Try looking for an option to turn off dnsmasq.
ok I got it to work.
Enable DNS forwarder and then set up your DNS server in System > General Setup (To the Pi IP). That will set the DNS server for the Pfsense box and it will hand it out to all DHCP clients too.
Glad it worked!
What box are you using for pfsense? Did you build it yourself?
