# Using VPN for Remote Work Without SSO Issues

Discover how to use a VPN for remote work without disrupting SSO and printer access, with examples and technical insights.

Before You Start Remote work has become increasingly common, and Virtual Private Networks (VPNs) are essential tools for maintaining security. However, using a VPN can sometimes interfere with Single Sign-On (SSO) systems and access to local network printers. This guide will walk you through configuring a VPN for remote work while preserving these functionalities. Prerequisites: - Basic understanding of network concepts - Access to VPN client software - Admin rights to configure VPN settings Security Warning: Always ensure your VPN configuration aligns with your organization's security policies to prevent unauthorized access. Technical Background A VPN creates a secure tunnel for data between your device and a VPN server, encrypting the traffic to protect against eavesdropping. However, this tunnel can also route all your network traffic through the VPN, which may disrupt local network services like SSO and printers. SSO systems rely on authentication tokens and cookies stored in your browser or application. If these requests are routed through a VPN server, they might appear to originate from a different location, causing authentication failures. Local printers, which typically use local network IP addresses, may become inaccessible because the VPN redirects traffic away from the local network. Split tunneling can address this by routing only specific traffic through the VPN while keeping local traffic intact. Step By Step 1. Identify the services you need to use through the VPN and those requiring local network access (e.g., SSO, printers). 2. Configure the VPN client to use split tunneling: - Windows: Use PowerShell Command: Add-VpnConnectionRoute -Name "AstraguardVPN" -DestinationPrefix "192.168.1.0/24" -PassThru - Linux: Edit the OpenVPN configuration file Example: route 192.168.1.0 255.255.255.0 net_gateway 3. Test SSO functionality by accessing your organization's portal and verifying login success without additional prompts. 4. Check printer access by printing a test page to a local printer on your network. Worked Example Let's configure a VPN connection with split tunneling for a network where local resources are on subnet 192.168.1.0/24, and the VPN server is at 10.8.0.2. Example: - For Windows PowerShell: Add-VpnConnectionRoute -Name "AstraguardVPN" -DestinationPrefix "192.168.1.0/24" -PassThru - For Linux (OpenVPN): route 192.168.1.0 255.255.255.0 net_gateway Configuration Or Command Reference - remote 10.8.0.2 1194 udp — VPN server endpoint and protocol - route 192.168.1.0 255.255.255.0 net_gateway — Direct traffic to local network - dev tun — Use a TUN device for routing - cipher AES-256-CBC — Encryption algorithm for secure tunnel - auth SHA256 — Authentication method for VPN connection Troubleshooting Symptom: SSO login fails repeatedly Likely cause: Requests are routed through VPN Fix: Verify split tunneling configuration and ensure local network traffic is excluded Symptom: Printer is not found Likely cause: Printer IP is not routed locally Fix: Add printer's subnet to split tunneling routes Symptom: VPN connection drops frequently Likely cause: Network instability or incorrect server configuration Fix: Check VPN logs for errors and adjust server settings as needed Related Concepts And Further Reading - Split Tunneling - VPN Protocols - Network Subnetting - Advanced SSO Configuration - Secure Remote Access Key Takeaways • VPNs secure remote work but can disrupt local network services. • Split tunneling allows specific traffic to bypass the VPN. • Proper configuration prevents SSO and printer issues. • Testing and troubleshooting are critical for a smooth setup. • Always align VPN configurations with security policies. FAQ Q: What is split tunneling? A: Split tunneling is a VPN feature that allows only specific traffic to be routed through the VPN, while other traffic accesses the internet directly. Q: Why doesn't my printer work over VPN? A: VPNs can route all traffic through the server, making local network printers inaccessible unless split tunneling is enabled. Q: How can I ensure SSO functions correctly with a VPN? A: Configure split tunneling to keep SSO traffic on the local network, ensuring authentication requests are processed normally.
