Port 80/443 and other Networking Ports blocked after enabling Hyper-V on Windows Server RRS feed

  • General discussion

  • I have Windows Server 2016 Datacenter on my server, running XAMPP for Apache/MySQL and Solarwinds Serv-U MFT for FTP. As a part of setting things up I set up inbound and outbound rules in firewall to allow various networking ports. Everything was working fine until I enabled Hyper-V. After the installation of Hyper-V and a successful restart, all networking ports were blocked, as checked from a port forwarding checker website. To confirm, those services were no longer accessible from the Internet. To confirm that Hyper-V is the culprit, I removed the service from the server manager and restarted (as it prompted me to do so), everything was back to normal again. Ports were working and every communication was back to normal. Just as another layer of confirmation I installed another version of Windows Server (2019 DC) on another computer, set up the same softwares and ports, enabled Hyper-V and the same thing happened again! I also tried to disable the firewall completely but got no luck. The problem was solved only after uninstalling Hyper-V completely. I would be grateful if someone helps me in resolving the issue.
