HYPER V 2012 R2

I have installed hyper v 2012 R2 on a dell r720XD, When my laptop is connected to the same router I can manage everything. I have a static IP connected to it.

But when I am at home or somewhere, I want to connect to it and manage it. I am simulating a situation since we are sending it to a colo location. NO VPN just a public IP.

At home I can not access disk management and the hyper v manager from my windows 8.

I can do RDP, access services, use mmc for firewall but not disk management and hyper v manager.

I modified the host to list the IP address of the server and the name.

I did the cmdkey, server, name, password

I did the

set-item wsman:\localhost\Client\TrustedHosts -value * -concatenate -force
I did the edit limits allow anonymous logon,
i did these
netsh advfirewall firewall set rule group=”Remote Administration” new enable=yes
 netsh advfirewall firewall set rule group=”File and Printer Sharing” new enable=yes
 netsh advfirewall firewall set rule group=”Remote Service Management” new enable=yes
 netsh advfirewall firewall set rule group=”Performance Logs and Alerts” new enable=yes
Netsh advfirewall firewall set rule group=”Remote Event Log Management” new enable=yes
 Netsh advfirewall firewall set rule group=”Remote Scheduled Tasks Management” new enable=yes
 netsh advfirewall firewall set rule group=”Remote Volume Management” new enable=yes
 netsh advfirewall firewall set rule group=”Remote Desktop” new enable=yes
 netsh advfirewall firewall set rule group=”Windows Firewall Remote Management” new enable =yes
 netsh advfirewall firewall set rule group=”windows management instrumentation (wmi)” new enable =yes
 net start vds
Is there a setting I missed so I can fully manage my server from another location?
