Can you set up a VPN for remote work off-grid?

Choosing the Right VPN Hardware

When setting up a VPN for off-grid remote work, it’s essential to select the right hardware. A dedicated VPN server or router with a built-in VPN server can provide a stable and secure connection. Popular options include the OpenWRT-based routers, such as the Ubiquiti EdgeRouter, and dedicated VPN servers like the pfSense. When choosing a VPN server, consider the number of concurrent connections, RAM, and storage requirements to ensure optimal performance. For example, a minimum of 2GB of RAM and 8GB of storage should be sufficient for a small to medium-sized home office.

Setting up the VPN Server

To set up the VPN server, you’ll need to configure the server software. Popular options include OpenVPN, StrongSwan, and WireGuard. OpenVPN is a widely used and highly configurable option, while StrongSwan is a popular choice for IKEv2 VPNs. When setting up the VPN server, ensure that you configure the server to use a strong encryption protocol, such as AES-256, and a secure authentication protocol, such as username/password or certificate-based authentication. You can also configure the server to use a split tunneling feature, which allows you to route specific applications or websites through the VPN while keeping other traffic local.

Securing the VPN Connection

To secure the VPN connection, ensure that you use a strong password and enable two-factor authentication (2FA) on the VPN server. Additionally, consider using a VPN kill switch, which will automatically disconnect the internet connection if the VPN drops. You can also configure the VPN server to use a secure DNS service, such as Unbound or DNSCrypt, to prevent DNS leaks. Finally, regularly update and monitor the VPN server’s software and firmware to ensure that you have the latest security patches and features.
