to configure the multiple environment setup I used the PDF (https://support.timextender.com/hc/en-us/articles/360001136526-How-to-configure-Multiple-Environments) , and everything works well when all the firewalls are turned off.
We have opened port 10001 and 5001, but when the firewall is turned on, my DEV environment can't connect with the Production environment.
My setup now is a Development server and a Production server.
When I want to connect from Development to Production, I see the servers negotiating on port 10001 and 5001. But after that, they continue to work with a port in the 64xxx range (examples: 64135,64177,64281 etc) e.g. a random port.
My firewall won't except this, and I would like to know if it is possible to work with a standard range / port so we can configure our firewall accordingly.
