Hi, I am using three websites example1.com, example2.com, example3.com. i am runing gunicorn py frame web app in example3.com on port 5000 where port is closed so i went to isp config firewall settings and added port 5000 and my server running in example1.com. while check in online port scan port 5000 is closed for example3.com. Thank you for @till for support for previous. Please assist me to open ports for domains
I believe ports can not be opened for one website only. Show the common issues results, https://forum.howtoforge.com/threads/please-read-before-posting.58408/ which should show firewall settings among other useful reports.
To me, this looks like a typical scenario where one would use a proxy in ISPConfig to make that software accessible to the outside instead of making this port accessible.
