Connect to Remote Hyper-V Host.md

Connect to Remote Hyper-V Host (over the internet - without domain/LAN)

1. Setup Ubuntu Server for OpenVPN (AWS) -
   • Install via https://github.com/Nyr/openvpn-install. Be sure to run bash script as root.
   • Download OpenVPN Connect Client on computer1 and connect to VPN using generated .ovpn configuration file
   • To create another .ovpn client config (for second computer), run bash script once again but this time select option #1 (Add a new client)
   • Download OpenVPN Connect Client on computer2 and connect to VPN using generated .ovpn configuration file
   • Edit /etc/openvpn/server/server.conf and append client-to-client to end of file
   • Restart OpenVPN service (sudo service openvpn restart)
   • Allow inbound traffic over UDP port 1194 in the server firewall (AWS: https://i.imgur.com/yEIwGhO.png)
2. Add Windows Defender Firewall exclusions to host AND client machine -
   • Open Windows Defender Firewall
   • Select "Allow and app or feature through Windows Defender Firewall" on the left sidebar
   • Locate "File and Printer Sharing" and check both boxes
   • Save and exit
3. Ensure host and client can communicate -
   • Open cmd.exe on the host and run ipconfig /all
   • Locate entry where description looks similar to TAP-Windows Adapter V9 for OpenVPN Connect
   • Take note of the shown IPv4 Address
   • Open cmd.exe on the client and run ping followed by the host IPv4 address
   • If you see Request timed out. return to step #2 and ensure you've followed along carefully; otherwise, you may proceed with step #4.
4. Configure Hyper-V host and client machines using instructions at https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/manage/remotely-manage-hyper-v-hosts#connect-to-a-windows-server-2016-or-windows-10-remote-host-outside-your-domain-or-with-no-domain (follow very carefully).
   • FQDN: fully qualified domain name AKA device name (found in Settings -> System -> About)
5. Ensure host and client Windows account username and password is identical (otherwise you may encounter an error something like: You do not have the required permission to complete this task.).
6. Map Hyper-V host IPv4 address to hostname -
   • Run Notepad/Notepad++ as administrator
   • Open HOSTS file (C:\Windows\System32\drivers\etc\hosts)
   • On a new line, enter the host IPv4 address followed by the host device name (example: https://i.imgur.com/mteeqQR.png)
7. Connect via Hyper-V Manager -
   • Open Hyper-V Manager on the client
   • Select "Connect to Server..." on the right sidebar
   • Check "Another computer" and enter the host IPv4 address
   • Click OK to connect!
