Can't access Device on PPTP VPN

I have created a pptp vpn that works. I can ping all remote devices on the remote network. I am using a pc client to connect to the remote vpn. I cannot, however, connect to a device that is forwarded to port 9192 on the remote mikrotik router. I can ping it fine, but I cannot type in the network address followed by the port and connect. When I am on site I can access the device.

for example:

192.168.1.10 will ping fine when connected via vpn

192.168.1.10:9192 will not connect to the device when connected via vpn

I want to be able to connect to this device via the remote vpn connection.

What am I doing wrong?
