I need help Port forwarding a steam game website is confusing

[preblem361]

So, I'm a major noob when it comes to this stuff and I know I'm missing something entirely obvious here but I'm going to ask anyway. This is revolving around the ports for icewind dale and icewind dale 2 (which never received a remaster) and here they are.

TCP: 2300-2400, 47624
UDP: 2300-2400, 47624

I know what I'm supposed to do with the first set of numbers (I think)

Start port 2300 - end port 2400. But what am I supposed to do with 47624?

[nullable]

I believe that would be an additional port. Ports don't need to be in a particular sequence or a range. Like http uses port 80, and https uses port 443. So I would make rules to allow icewind dale 1/2 be able to access ports 2300-2400 and port 47624.

Yes ports, can be five digits long. Some api I'm working on runs on localhost port 44365 for example.

Youre supposed to forward 47624 as well. If your router insists on a range, make it 47624-47624.
