Is it possible to fix the active port number for data session on active mode?

You can vote for it there.

It's implemented now.

Can you send me an email, so I can send you back a development version of WinSCP for testing? Please include a link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

As advised, I sent you an email for the request of the development version of WinSCP.

Dear Martin,

Thank you for the development version of WinSCP.
I confirmed that the active port number can be specified by the configuration.
When will this new version be released?

We do not have any release date set yet.
