Using SSH Tunnel to Access vCenter Server

I need to access my Vcenter Server remotely as from time to time I practice on my homelab even if I am not at home.

My Battlestation

Slowly I am building a computer system and finally I have completed it! I have started with a Lenovo Thinpad T420s and maxxed out the upgrades - 16GB RAM for vmware workstation virtualization, SSD for primary OS (Linux) and storage for virtual machines, another SSD for 2nd OS (Windows), and traditional HDD for backup storage. The most noticeable upgrade is the SSD. Even if the RAM is maxxed out but if using traditional HDD, the system is still slow.
