In general, TP-Link Wi-Fi Router has three VPN function scenarios, including working as VPN server, connecting to remote VPN server as VPN client and supporting VPN Pass-through. Now this article will summarize and present these scenarios in a row.

Case 1: Working as a VPN Server

Q1: What should I do if I can’t connect to my VPN server?

As a server, the router needs a public IP address in order to be able to guarantee the remote connection.

1). Please kindly check if you have a public WAN / Internet IP address.

2). Also, we suggest setting your public WAN/Internet IP address as a static IP address. If your ISP refuses to set it as static, you are suggested to use the DDNS service on your TP-Link router to associate your dynamic public WAN/Internet IP address with a domain name. You can refer to How to setup TP-LINK DDNS on TP-Link Wireless Router.

Q2: What kind of VPN server is supported by TP-Link Wi-Fi router?

A: Open VPN and PPTP VPN, but it is also different from different models.

Q3: When connecting to a VPN server, how do I do if I can’t get any responses when testing TP-Link Wi-Fi router (VPN server)?

Q4: After connecting to the VPN server, how do I do if I can’t ping/access the internal local resources/servers on the LAN of the TP-Link router?

1). First, check the firewall and antivirus software on the internal servers. Generally, the firewall thinks VPN packets are not secure, so your computer may block these packets. For Windows PCs, disabling the public and private network firewall will come in handy.

2). Check if the internal server has been built successfully. Please use the machine in the same subnet as the internal server to visit your host/server, if this machine can’t reach the host, which means the host’s network setting is wrong and please reconfigure it.

Case 2: Connecting to the remote VPN server as a VPN client

Q: Does TP-Link Wi-Fi Router support 3rd party VPN server provider like ExpressVPN and Nord VPN?

A: When setting up a VPN tunnel, there are control links and data links. Data links have two different modes: unencrypted and unencrypted. Our TP-Link Wi-Fi Router can only support unencrypted data links. However, most of the third-party VPN server provider, such as Nord VPN, Express VPN, etc., use encrypted VPN connection, which means that TP-Link router does not support most of the third-party VPN server provider now.

Case 3: VPN traffic support

About VPN Pass-through, it means that clients connected to TP-Link router make VPN telephony for themselves to VPN server at the remote end, TP-Link router can only allow this kind of VPN packet through itself to complete VPN connection. Thus, for this kind of scenario, what a TP-Link router can do is only allow relevant VPN packets and not block this type of data that comes through the router.

Q: How do I do if there is no internet connection after connecting to the VPN server?
