OpenVPN Configuration for LAN to Client Connection for Remote Support

I am trying to configure the OpenVPN server to allow me to ping VPN clients from the LAN.

I need to be able to use remote desktop from the LAN to connect to Clients for remote desktop to fix laptop issues remotely.

I am using 3.0.0.4.270.24 (Merlin build) on an RT-AC66U.

How do I go about setting this up? I currently have OpenVPN set up on the router that lets clients connect and interact with the LAN.

The OpenVPN server is currently set up with the follow gui options:
Start With Wan -- Yes
Interface Type -- Tun
Protocol -- UDP
Port (default)
Firewall -- Automatic
Authorization Mode -- TLS
Extra HMAC Auth -- disabled
Poll Interval -- 0

TLS Renegotiation TIme -- -1
