Hello Danny,
I’m going to post it again here.
You will need to use either a Inbound Access or Nat Mapping.
The following article describes how to set up an Inbound Access.

You can use NAT Mapping as well. However, It will be one to one NAT and all the ports will be forwarded to the device.

The following article describes how different these functions are.

Hello Luke,
Could you tell us where your existing 3rd party VPN device is located at? If it is located right behind the balance, you can follow the same setup as Danny needs to.
If you have any questions, please let us know.
Best Regards,
Haruki
