Open ports reported on site-- security risk?

Hi. I am trying to get xplane 11 and autoortho to work. I've edited the fuse.conf to allow others, like I saw on Github. The problem I have is that in the Log.txt, it reports that RAKNET has an error 5, that the socket is occupied. Someone posted that autoortho has a default port of 5000, and that changing that may solve my problem. I posted the results of:

sudo netstat -ntlp | grep LISTEN

tcp 0 0 127.0.0.1:27060 0.0.0.0:* LISTEN 3439/steam
tcp 0 0 127.0.0.1:41401 0.0.0.0:* LISTEN 3439/steam
tcp 0 0 0.0.0.0:27036 0.0.0.0:* LISTEN 3439/steam
tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN 5855/cupsd
tcp 0 0 127.0.0.53:53 0.0.0.0:* LISTEN 981/systemd-resolve
tcp 0 0 127.0.0.1:57343 0.0.0.0:* LISTEN 3439/steam
tcp 0 0 127.0.0.1:37869 0.0.0.0:* LISTEN 3439/steam
tcp6 0 0 ::1:631 :::* LISTEN 5855/cupsd

And so was wondering if this was a bad move for security's sake? In addition to this concern,
since I already posted this info, can anyone tell me what port I should use?
