I think that fixed port is necessary.
Because, it have a problem of security.
Don't know a number of a port opening out...
then, can't understand the port with attacked possibility.
Even if we perform an operative design before guest making,
We don't understand we are using any number, and which number was used.
It may be a very small niche usecase.
But, I think security is not an at all small problem.
So, I think that selection of a fixed port number is better.
