      I can't seem to get openvpn to use the dns sever ive set for it.

      I have openvpn dns set to 10.0.0.1 (which is Pfsense) and the dns on pfsense is set to 10.0.0.222 (which is pihole) the phones still show Ads/

      when i set openvpn dns to 10.0.0.222 the Ads don't show but the logs show its used the virtual IP 10.0.2.3 not the real IP 10.0.0.117

      which was it correct? or do i have it set up completely wrong?

      Thanks

        DNS Resolver in Forwarding Mode or what are you using?
        Is it working for your LAN Clients?
        Check the OpenVPN client Log to see what exactly is pushed.

            You should see something like this in your client log
            Mon May 11 19:18:59 2020 PUSH: Received control message: 'PUSH_REPLY,...,dhcp-option DNS 172.29.33.101,dhcp-option DNS 172.29.33.102,...'
            I push via Client CSO, the Server option DNS Server enable should do the same though.

                        Again, check the CLIENT side log to check what is pushed or not pushed.

                            DNS traffic to pfSense is allowed with Firewall Rules?
                            Can you post your Rules via screenshots?

                                Fixed the issue if I don't set a dns in the openvpn setting it works fine and still used 10.0.0.1 as a dns thanks for the help!
