Background and Scenario:

Sometimes, we might need to use the L2TP VPN client to connect to an intranet PC via VNC for handling some office tasks.

Answer:

Please refer to the below lab:

Topology:

(WAN:10.214.48.135) PC : L2TP client (192.168.50.1) => (WAN:10.214.48.25)USG Flex200 => LAN1=>PC :Ultra VNC server(192.168.1.121)

Firstly, please confirm the L2TP client is already connected to USG  Flex200.

After establishing an UltraVNC connection from the L2TP client (192.168.50.1) to the LAN1 PC (192.168.1.121) on port 5900, enter the VNC password to successfully access the LAN PC's remote desktop.
