![]() ![]() Reasons to use multiple VPN arrangements include the following: Advantages and disadvantages of using multiple VPNs Check each application to see if it supports multiple VPNs. For example, two VPN applications available for Edge are VPNizer and Ivacy. A VPN chain uses more than one VPN server, providing greater security for the connection.Īnother way to set up VPNs is to use browser extensions - specialized applications that can be accessed via a device browser, such as Microsoft Edge. It is possible for a double VPN service provider, such as NordVPN, to support multiple VPNs from a single device, with appropriate configuring of the NordVPN Double VPN feature. This arrangement is also referred to as a double VPN, doublehop VPN or multihop VPN. This strategy provides greater security for a VPN connection because of the double encryption. Create a VPN chain - or double VPNĪ double VPN uses multiple VPNs in a chain arrangement by routing through more than one VPN server. This can affect processing speeds as more VPNs are added. Note that the system's IP address initially routes through the computer and then routes to the VM. This approach can, in effect, create two tunnels. Once the VM is launched, install free software, such as OpenVPN, in the VM. If more than one OS is available, such as Windows and Linux, consider using Linux for the VM. One technique for using multiple VPNs together is to run one VPN on the primary OS and install the other VPN on a VM that runs in the device. A review of issues associated with using rasphone.pbk showed that the initial VPN set up as desired, but the second lost its authentication parameters and required manual reentry of username and password. Once this set of connections has been established for the first VPN, the second VPN will attempt to use the same routes, causing errors.įor example, Microsoft offers a networking utility called rasphone.pbk, which is designed to facilitate multiple VPN sessions from a single device, while retaining the unique settings of each connection. The first VPN establishes various routes with lines of netmasks that take over a default gateway. This problem is because the two VPNs compete until one VPN wins, which results in only one running VPN. While one VPN may appear to be performing properly, the second may display routing errors. It can be more challenging to run multiple simultaneous VPNs than to configure two VPN providers and connect them. How to use multiple VPNs together from one system Other traffic - with no VPN - goes over the internet to the remote locations. For example, the VPN policy might say all traffic sent to 192.168.0.0/24 goes over a VPN tunnel to the main office. ![]() It's also possible to configure a single VPN client with a policy that permits the client to reach more than one destination, which is called split tunneling. One way to ensure this is by using encryption. As such, network managers must make arrangements for traffic that uses non-VPN connections to ensure the information being accessed is secure, its confidentiality and integrity are protected, and its availability is assured. Security and availability are primary drivers for VPN usage. ![]() However, if they need to access additional web-based services, they must use a non-VPN connection to the remote host. Remote workers normally use a VPN tunnel to access their primary work systems and resources. With VPN split tunneling, a single VPN client can reach more than one destination. The image below depicts how that might work in practice. Installing a second instance of VPN software and an additional network interface card probably won't work, as the VPN clients may overlap and interfere with each other. Can that user connect via the same VPN tunnel? In most cases, the answer is no because the VPN software generally supports only one connection at a time. Now, suppose the remote user wants to connect to another resource offered by the company. The VPN - whether initiated by a physical appliance or software application - provides access control, security and other mechanisms for a secure connection. Can two VPNs be used at once?Ĭonsider the following scenario: A remote laptop normally connects to host-based systems via a VPN that uses the internet as the transmission medium. Finally, it discusses the advantages and disadvantages of using multiple VPNs. It explores scenarios where multiple VPN sessions provide value to individual users, as well as the risks associated with expanded remote access. This article examines the pros and cons of setting up two VPN connections at the same time from one remote device. ![]()
