Sharing VPN SSL Client connection in home-network

Question

We are currently using VPN SSL Clients for our employees to give them access from their homes to office-workstations which works pretty well. 
 Some of our users would need to connect a secondary internet device (game development console) which is currently hooked up to their home network. 
 Now this game console would need to connect to the office network but has no option to use a VPN client software. 
 
 I tried to simply turn on "internet sharing" in Windows 10 on the "Sophos SSL VPN Adapter" but that dis-configured the Ethernet adapter (which is understandable) that is being used for accessing the home-router. This resulted in loosing the internet connectivity in general. 
 Would it help to install a secondary ether network card into the pc and use it for "internet sharing" and hook the game console to this lan port? 
 Or is there a way to create a secondary network card that physically shares the network port but can be configured for internet sharing without disturbing the primary lan connection? 
 Are there any other vpn options to bring the game console into the office-network without installing a VPN (client/tunnel) capable hardware router?

ChrisSoukup said: Do I actually have to replace the internet router with the RED device or can it also just sit somewhere on the LAN and needs a forwarded port from outside? 
 You just hook it up to a LAN port with internet connection, no port forwarding needed, it phones home to a Sophos server and sets up itself with what you configure in the UTM. 
 Can it deal with dynamic public ip address, too? 
 yes, I use two RED15s for remote IP phones (one of them in China, works like a charm). 
 You can of course also enable a MAC filter for the REDs so only the console can connect.
