The Client's computer that is connected to SSTP VPN or L2TP (Windows Server 2019) is visible to internet WAN IP address instead of server WAN IP Address. For example, when putting keyword "what is my IP address", it shows my service WAN address instead of remote VPN server's IP address. How can I configure Windows Server 2019 to hide the client's service WAN address when the VPN wan address is shown on client?
