Fix: VPN Error 809 on Windows 10 & 11

You need to open the ports on your firewall or router, depending on which VPN protocol you’re using.

• Port 1723 over TCP for PPTP
• Port 500 or 4500 over UDP for L2TP/IPsec or IKEv2/IPsec

If this is not possible, deploy the SSTP- or OpenVPN-based tunnel on your VPN provider.

This allows the VPN connection to work across the firewall, NAT, and web proxies.
