Hyper-V Manager over a VPN not able to connect

I have setup a Hyper-V server in a workgroup setup.

I have used the following steps to achieve this, which is all working on my local LAN.

My router supports multiple LANs, and I am able to use the Hyper-V manager between them as well.

What I have not been able to get to working is when trying to access the server with the Hyper-V Manger over my VPN.

Steps I used to allow Management access for WorkGroup:

On the Hyper-V Server:
Ran PowerSHell as Administrator
Ran: SConfig.cmd
Selected options 4 Configure Remote Management, then 1 Enable Remote Management
Selected option 3 Add Local Administrator, added Windows Username being used on the Remote Computer

On the Remote Client PC:
Ran PowerShell as Administrator
Ran the following commands to add Hyper-V server as turster host, and add administrator password

Set-Item WSMan:\localhost\Client\TrustedHosts -Value 192.168.1.100 -Concatenate
cmdkey /add:192.168.1.100 /user:administrator /pass:

Ran this to check host were added:
Get-Item WSMan:\localhost\Client\TrustedHosts

Ran: dcomcnfg
Open component services --> computers
Right-click -> my computer -> properties
Select "COM SECURITY" tab
Under "ACCESS PERMISSIONS" select "edit limits"
Select "ANONYMOUS LOGON", and tick "remote access" under ALLOW


So on my local LAN, I can use the Hyper-V to access the server 192.168.1.100 from other LAN on 192.168.5.10.

But when I try this from a remote PC via a VPN, which is on IP 10.0.0.10, it does not seem to be able to even see the Hyper-V service running.

I can ping and RDP to the server hosting the Hyper-V system, but the Hyper-V manager is not able to connect.

I tried turning off all the firewalls, but still could not get any joy.

All my desktop logins are using the same Username and Passwords.

Thought to try and see if someone could suggest anything that may assist me with this.

Thanks in advance for any comments.
