DNS Server Return/Lookup when trapped

[gwaitsi]

i am using DHCP which sets the DNS server as pfsense, for some clients like andoid and windows (particularly with antivirus/firewalls) they set their own DNS overrides. e.g. comodo and avast

I created a NAT Rule;

Interface: LAN
Protocol: TCP/UDP
Source: LAN Net
Src Port: *
Dest: !pfsense
Dest Port: 53
NAT IP: LAN Net
NAT Port: 53

I block 53 from the WAN/VPNs and the rule works i.e. all PCs can resolve even with DNS overrides.

Only one small thing i notice.
When using nslookup to either resolve the host or the IP, the server is returned as unknown
e.g.
nslookup google.com
Server: Unknown
Address: 156.154.70.22
Non-authoritative Answer
Name: google.com
Address: 172.217.19.206

If the DNS is set to pfsense, the server name and address will be pfsense and the address of pfsense

Am i able to return the DNS server name via a rule (even if trapped) or should i just ignore?
