Original GitHub issue: https://github.com/quasar/Quasar/issues/621

I have seen that the client will cycle through a list of ports attempting to connect to the server with each - so far I have not been able to set this to a fixed port that I intend to use for testing. Anyone able to advise?

This was mentioned in the old Quasar chat room that we had -- does anyone remember?

I'm not sure if I understand your question correctly, but when you only enter one host:port combination, the client will always try to connect to this and not cycle through others.
github.com/quasar/QuasarRAT@15b01116bf/Client/Config/Settings.cs (L14)

Or do you mean the local tcp client port? This is being decided by the system (see here) and I'm not sure why you would like to stick with one port there.

It was mostly for testing purpose to test around outgoing firewall issues but that is fine thanks.
