Thank you for the clarification.
I think I have mine correct then.
There's no need to change the LAN computer's listening port of 80, which I was confused with.
However, having my LAN computer's setup like that, I still receive the errors:
Browser:
No remote browser access to security server on publicWANIP:8061.
Remote browser access to security server on publicWANIP:8063.
SSH:
$ ssh ubuntu@publicWANIP -p 8061
ssh: connect to host publicWANIP port 8061: Connection refused
$ ssh ubuntu@publicWANIP -p 8063
ssh_exchange_identification: Connection closed by remote host
TeamViewer:
TeamViewer to 192.168.1.40 blue, but won’t connect.
Now TeamViewer to 192.168.1.40 connects, but 192.168.1.120 turned off?
TeamViewered into 192.168.1.120, the remote connection turned off.
Traffic analyser:
Tested packet capture: LAN computer > pfSense > Diagnostics > Packet Capture > Start > remote computer (I'm on this) > Terminal > $ssh ubuntu@publicWANIP -p portNumber > Enter > LAN computer > pfSense > Stop.
No packets reaching the pfSense WAN.
I'm now stuck remotely and will need to physically go to the local computers for access, to try again tomorrow.
