Connecting to your agency’s network from home or while traveling requires a Virtual Private Network (VPN). Government agencies use several enterprise VPN solutions, with F5 Big-IP, Palo Alto GlobalProtect, and Cisco AnyConnect being the most common. Here’s how to set up each one on your Mac.
Before You Begin
VPN access on government systems requires proper authorization. Before attempting to configure VPN:
- Ensure you have an approved telework agreement on file
- Verify your Mac is enrolled in your agency’s MDM system
- Have your PIV/CAC card and reader ready if required
- Know your agency’s VPN gateway address
- Confirm your network account is enabled for remote access
Cisco AnyConnect Setup
Cisco AnyConnect is widely used across federal agencies, including DoD and civilian departments.
Installation
Download AnyConnect from your agency’s software portal or Self Service application. Do not download from Cisco directly, as government versions include specific security modules and configurations.
Configuration Steps
- Launch Cisco AnyConnect Secure Mobility Client from Applications
- Enter your agency’s VPN gateway address (provided by IT)
- Click Connect
- Select your authentication method (usually certificate + password or CAC)
- If using CAC, insert your card when prompted and enter your PIN
- Accept the security banner acknowledging authorized use
Troubleshooting AnyConnect
If AnyConnect fails to connect, check that no other VPN client is running. AnyConnect conflicts with most other VPN software. Also verify your CAC certificates are current by checking them in Keychain Access.
Palo Alto GlobalProtect Setup
GlobalProtect is increasingly popular in government due to its integration with next-gen firewalls.
Installation
Install GlobalProtect from your agency’s managed software center. The client should auto-configure with your agency’s portal address during MDM enrollment.
Configuration Steps
- Open GlobalProtect from Applications or the menu bar
- Enter the portal address if not pre-configured
- Click Connect
- Authenticate with your credentials or smart card
- Complete MFA if prompted (usually via authenticator app or SMS)
GlobalProtect Features
GlobalProtect often runs in “always-on” mode on government Macs, meaning it connects automatically whenever you’re off the agency network. This ensures continuous protection and policy enforcement.
F5 Big-IP Edge Client Setup
F5 Big-IP is common in agencies using F5 application delivery infrastructure.
Installation
The Big-IP Edge Client is typically installed via your agency’s web portal. Navigate to your VPN portal in Safari, authenticate, and follow prompts to install the client component.
Configuration Steps
- Open F5 Big-IP Edge Client
- Enter your agency’s VPN server address
- Click Connect
- Enter credentials when prompted
- Complete any additional authentication factors
Common VPN Issues and Solutions
Connection Drops Frequently
Check your home internet stability. Government VPNs often have strict timeout policies. Also ensure your Mac isn’t going to sleep, which disconnects VPN. Adjust Energy Saver settings to prevent sleep while on VPN.
Slow Performance Over VPN
Split tunneling may be disabled, routing all traffic through the agency network. This is a security requirement for most federal agencies. Use approved cloud services that may bypass VPN for better performance on non-sensitive work.
CAC Not Recognized
Ensure your CAC reader drivers are installed and the card is properly seated. Try removing and reinserting the card. Check that your certificates aren’t expired in Keychain Access under “My Certificates.”
VPN Client Won’t Launch
Check for macOS updates that may have affected the VPN client. Some VPN software requires specific macOS versions. Verify the client version is approved for your current macOS version with your IT department.
Security Reminders
When using VPN from home or public locations:
- Never leave your Mac unattended while connected to VPN
- Avoid public WiFi; use your phone’s hotspot instead
- Disconnect VPN when not actively working
- Don’t share your VPN credentials or allow others to use your connection
- Report any suspicious connection behavior to your security team
A properly configured VPN connection keeps your government work secure while enabling the flexibility of remote work. If you encounter persistent issues, your agency IT help desk can provide support specific to your environment.
