How to use remote connect to linux server with parallel sessions?

Soniak 1

Hello,

I have server on Linux. I have in the same LAN workplace on Linux also, and one workspace outside on Windows.

My goal is: connect to Linux server from both places and have option to work parallel as window's rdp. What software can you offer?

Also, I have trouble for windows workspace. It is outside the NAT. I can't configure NAT for Linux server. I need software with internet-id or something like. I tried Teamviewer, but if we campare with windows rdp it's really weak: I can't work parallel with other person. It uses GPU.

What can you advice to work from outside the NAT with parallel sessions?
