TRENDnet User's Guide Virtual Private Networking (VPN) Creating a Virtual Private Network (VPN) Network > VPN What is a VPN? A VPN provides secure communications typically over the Internet by creating a secure tunnel between two or more VPN routers (gateways) also known as a site-to-site VPN or between a single client computer and a VPN router (gateway) also known as a clientserver VPN. On your router, the following types of tunnels can be created: Site-to-Site VPN - Connects two or more VPN routers (gateways) allowing the LAN network from each router to securely communicate to each other over the Internet. Tunneling Methods: IPsec Client-Server VPN - A single client computer or device with VPN client software installed connects to a VPN router (gateway) allow the single client computer or device to securely communicate to the LAN network of the VPN router over the Internet. Tunneling Methods: IPsec/SSL(OpenVPN)/PPTP/L2TP/L2TP with IPsec © Copyright 2019 TRENDnet. All Rights Reserved. Limited Warranty Tunneling methods supported by your router: SSL (Secure Socket Layer) VPN - This type of VPN can be used for Client-Server VPN only. There is support for both Layer 3 and Layer 7 network access with SSL VPN but your router only supports Layer 3 access. Additionally, your router utilizes the use of OpenVPN® for SSL VPN. The third party software client is available for free download using the following link for both Windows® and Linux operating systems https://openvpn.net/index.php/opensource/downloads.html. IPsec (Internet Protocol Security) VPN - This type of VPN can be used for either Site-to-Site VPN or Client-Server VPN, however, the most common application for this type is a Site-to-Site VPN. This type of VPN can provide highest degree of security. For a Client-Server VPN, typically, a third party VPN client software is required to be installed and configured and can be difficult when installing and configuring on VPN client computers. This VPN type can provide the highest degree of security. PPTP (Point-to-Point Tunneling Protocol) VPN - This type of VPN can be used for Client-Server VPN only however both server mode and client mode are supported on your router. Most computer operating systems already include a pre-installed PPTP VPN client software that can be easily configured which eliminates the need for an additional third party VPN client software to be purchased and installed. Since it provides less security overall than IPsec VPN, it is not recommended for a Site-to-Site VPN. L2TP (Layer 2 Tunneling Protocol) VPN - This type of VPN is very similar to PPTP VPN as it is most commonly used for a Client-Server VPN, pre-installed on most computer operating systems and easy to configure, and provides less overall security than IPsec VPN. Most of the current operating systems with L2TP VPN client software pre-installed use L2TP VPN in conjunction with IPsec VPN to improve the overall security provided. This router does not support the L2TP over IPsec VPN method. Important Note: For any tunneling or VPN method used, to avoid IP address conflict and to ensure connectivity, it is required that each end (LAN IP network or single client) of the VPN tunnel is configured with a different IP network or subnet. 62
