Just review what is listening on what port, that is key. Try to stick to ports that are not sharing the same port as other applications (UDP only) with TCP applications cannot listen on the same port so just ensure those ports are not open. Usually people will open ports like 3016-3020 when they never realized one service is listening on 3019.

Unfortunately I'm not sure I understand. Avoid ports that are UDP only? I see port 3019 is used for CIFS a Windows network file sharing protocol. To my knowledge CIFS usually isn't used over the Internet so it sounds like a port you'd want to avoid (because bots would probably scan for it).

 

It'd be nice to locate a clean range of ports so I don't have to make multiple entries in the router when I have to skip ports.

 

Edit:

Wait CIFS was port 3020. My bad.

The ports I mentioned were just examples and UDP is usually the only apps that listen on the same port, UDP was just a point to make sure you know what is listening on your device. I just gave out random ports I didnt realize CIFS ran off one lol. 

 

I used to use a site that I would show common ports. You can manually type in a port too and it would tell you what port an app is commonly used with:

Good ol wikipedia is useful too:

So in short, avoid ports that are being used by other programs or protocols. Does this mean it'd be in my best interest to find a range of unassigned addresses?

 

Just found an TCP/UDP unassigned range of 31000-30015 for now that'd fill my needs.
