@bre

and the last, you should remember that many people are behind fascist firewall, only ports 80 and 443 allowed, it is not possible to use putty (port 22) or anything else, so, the free network client on users PC should be able to avoid such control, users should be able to choose the port or the client should be created to use port that can’t be blocked, for example 443, nobody blocks 443. portable client and port 443 are solution for fascist network admins.

You can set a port if you wish otherwise we hole punch. This works behind many firewalls and will improve. I any case the use case you ask for here is covered
