Routing explicit IP through VPN - road warrior

[rcoleman81]

I have a network, here's the details:
VPN network: 192.168.47.0/24
Office: 192.168.46.0/24
pfSense:
              WAN: 192.168.46.5/24
              LAN:  192.168.47.1/24

Office Gateway: 192.168.46.254

I have a customer who has a firewall rule that only allows me to RDP from the office IP. I want to make the OpenVPN route traffic to that IP address through the VPN while leaving all other public internet traffic to route through the network I am on.

I have tried a lot of iterations but every single one I do on a traceroute it dies at 192.168.47.1.

RDP IP: 1.2.3.4

So, I've tried:
              push "route 1.2.3.4 255.255.255.255 192.168.47.0";
              push "route 1.2.3.4 255.255.255.255 192.168.46.0";
              push "route 1.2.3.4 255.255.255.255 192.168.46.254";
              push "route 1.2.3.4 255.255.255.255 vpn_gateway";

All have the same result.

I want it to route from LAN to WAN and push through the Office route to the internet.

What should I enable to do this?

This is a road warrior setup with selective routing through the VPN (it allows access to VPN clients, Office device and another remote office worth of devices. This all works right now).
