VPN for Remote Work: Setup Guide

Learn how to set up and use a VPN for secure remote work, including corporate VPN types, split tunneling, and best practices.

Why Remote Workers Need a VPN

Working remotely means connecting to corporate resources from potentially insecure networks -- coffee shops, hotels, airports, and home Wi-Fi. A VPN creates an encrypted tunnel between your device and the corporate network, ensuring that:

  • Data in transit is encrypted -- Even on untrusted Wi-Fi, your traffic is unreadable to eavesdroppers.
  • Internal resources are accessible -- Intranet sites, databases, and file servers become reachable as if you were in the office.
  • Company IP policies apply -- Your traffic appears to originate from the corporate network.

Corporate VPN Types

Remote Access VPN

The most common type for remote workers. Each employee's device runs a VPN client that connects to a VPN gateway at the office or cloud:

10.0.0.0/25   → Dept A    (10.0.0.1 – 10.0.0.126)    126 hosts
10.0.0.128/26 → Dept B    (10.0.0.129 – 10.0.0.190)    62 hosts
10.0.0.192/28 → Servers   (10.0.0.193 – 10.0.0.206)    14 hosts
10.0.0.208/30 → P2P Link  (10.0.0.209 – 10.0.0.210)     2 hosts

Popular solutions: Cisco AnyConnect, OpenVPN Access Server, WireGuard, Palo Alto GlobalProtect.

Site-to-Site VPN

Connects entire office networks together. Not used by individual remote workers, but relevant for branch offices:

Cloud-Based VPN (ZTNA)

Modern alternatives like Cloudflare Access, Zscaler, and Tailscale replace traditional VPNs with Zero Trust Network Access. Instead of routing all traffic through a central gateway, they verify identity and device posture for each request.

Setting Up WireGuard for Remote Work

WireGuard is lightweight, fast, and increasingly popular for corporate VPNs:

Split Tunneling for Remote Work

Routing all traffic through the corporate VPN adds latency and consumes bandwidth. Split tunneling routes only corporate-bound traffic through the VPN:

  • Corporate resources (intranet, databases) -> through VPN
  • General internet (YouTube, personal browsing) -> direct connection

This reduces VPN server load and improves the employee's internet experience.

Security Best Practices

  • Require MFA for VPN authentication -- username/password alone is insufficient.
  • Keep VPN clients updated -- VPN software vulnerabilities are actively exploited.
  • Use always-on VPN with a kill switch when handling sensitive data.
  • Enforce device compliance -- Only allow devices with updated OS, active antivirus, and encrypted storage.
  • Monitor VPN connections -- Log authentication attempts and flag unusual access patterns (login from unusual locations, off-hours access).
