I don't use pfsense so I don't know if this applies to your situation..

On linux ports <=1024 can only be opened by root. I use port 80 and 21 for my BBS so I use setcap to give my application (bbbsd in this case) the
capability to open and use these ports, like so..

sudo /sbin/setcap 'cap_net_bind_service=+ep' bbbsd

The above command will need to be run whenever your application is updated or reinstalled.

The Synchronet wiki talks about this and the authbind method to acheive this.
