Thanks for your advise. I have enabled UDP port 4500 both inbound and outbound, but no luck yet. I have studied the article you provide and noticed that it applies to Windows 7 and Windows Server 2008 R2, instead of Windows Server 2012 R2. Actually I did the setup step by step by learning this article: HOW TO INSTALL VPN ON WINDOWS SERVER 2012 R2 For L2TP/IPSEC VPN connections, you need to open UDP port 500 for Internet Key Exchange (IKE) traffic, UDP port 4500 (IPsec control path) and UDP port 1701 for L2TP traffic. IPsec ESP traffic also uses IP protocol 50. SSTP connections use TCP port 443 (SSTP traffic to/from the VPN server) Create a Windows Firewall rule to open port PPTP VPN. Go to Control Panel>System and Security>Windows Defender Firewall and click Advanced settings. Select Inbound Rule from the left navigation and New Rule on the Actions Menu. Select Port as Rule type and click Next. How to Setup VPN using PPTP Port forwarding is a technique used to enable incoming internet connections to reach your device when using a VPN. It is necessary because most VPNs use an NAT firewall to stop users falling victim to malicious incoming connections. This is a useful security feature, but it is unfortunately unable to distinguish between incoming connections you don't want and those that you do. Firstly, choose "Port", and then click on "Next". Most VPN service providers use these ports: 500 and 4500 for UDP and port 1723 for TCP. If these ports do not work, then you will need to contact your VPN administrator to find out which port number you should use. We will just use TCP 1723 as an example for illustration purposes. A VPN port is a networking port that is used within a VPN infrastructure. They are the logical ports that enable VPN traffic to pass in and out of a VPN client or server device. -> Asking a search engine like so: "VPN port number" will tell you straight away. I've tried going into my network settings and setting up a port forward there. -> You must create a tunnel for port 1723 in your router. I've also tried to add a rule to the firewall to allow this port to make the connection, but I still cannot connect remotely.

How to Set up an L2TP/IPsec VPN Server on Windows. In this tutorial, we’ll set up a VPN server using Microsoft Windows’ built-in Routing and Remote Access Service. To do this, we’ll be using the Layer 2 Tunnelling Protocol (L2TP) in conjunction with IPsec, commonly referred to as an ‘L2TP/IPsec’ (pronounced “L2TP over IPsec”) VPN.
