Hello. Is my first post here an until now i’ve learned much from here.
I have an network witch is working well. Untill few days ago i was able to connect from home to Server at work for maintenance. Because the main server has 3389 default port for RDP, i set for the other 2 servers ports 3390 and 3391. I was able to connect to my other servers (x.x.x.x:3390 and x.x.x.x:3391) with no issues. Now, i can’t connect anymore. Port forwarding has no changes and other ports are forwarded ok. For example i set for test the port 32400 for PLEX and is open. The rest are closed. I observ that the ports 21, 22, 23 or other common ports are closed. I see that the ports 22 have closed from default, but i don’t need it and i will leave like this. Can you help me with this issue? In last 2 months i work from home and is very hard without this connections. I don’t want to use teamviewer or other apps for remotely control my servers. Thank you.
My config.
My interest is for Server DC1 and Server DC2 mostly.
