How to set up a VPN for secure remote work

· Category: Networking

Short answer

A VPN creates an encrypted tunnel between your device and a private network, allowing secure remote access as if you were physically connected to the office LAN.

Steps

  1. Choose a solution: Select between self-hosted options like WireGuard or OpenVPN, or enterprise services like Cisco AnyConnect.

  2. Install the server: Deploy the VPN server on a gateway device or cloud instance. Configure IP addressing and routing.

  3. Generate credentials: Create certificates, pre-shared keys, or user accounts. Distribute client configuration files securely.

  4. Install clients: Install the VPN application on remote devices. Import the configuration.

  5. Connect and verify: Establish the tunnel and verify your IP address reflects the corporate network. Test access to internal resources.

Tips

  • Use WireGuard for simplicity and modern cryptography.
  • Enable split tunneling carefully to avoid routing all personal traffic through the company.
  • Require MFA for VPN authentication.

Common issues

  • MTU misconfiguration causing fragmented packets.
  • DNS leaks exposing browsing history.
  • Firewall rules blocking the VPN protocol or port.
