Cisco AnyConnect is a popular VPN client, especially common for remote workers connecting to corporate networks. A "split exclude" configuration, available on the Mac version, allows you to control which traffic doesn't go through the VPN. Normally, all your internet activity is routed through the VPN server. Split exclude creates exceptions, letting some apps or websites bypass the VPN tunnel and connect directly. This can improve performance for non-work-related activities while keeping sensitive data secure.
Split exclude is useful when:
You need access to local network resources (like a printer) while connected to the VPN.
Certain websites or applications perform poorly when routed through the VPN. Streaming video or online games are common examples.
You want to separate work and personal internet traffic for privacy or performance reasons.
By excluding specific traffic, you can maintain a secure connection to your company's network without impacting your everyday browsing experience.
The split exclude feature isn't something you typically configure yourself. It's usually set up by your IT department. However, you can check if it's enabled and see which applications are excluded.
Open the Cisco AnyConnect client.
Look for a "Statistics" or "Details" section. The exact wording varies by version.
Check the "Route Details" or similar tab. This should list the excluded networks or applications.
If you need to add or remove an exclusion, contact your IT support team. You usually can't modify these settings directly.
While you might not directly control the exclusions, understanding the principles helps. Common exclusion types include:
Specific Websites: Traffic to certain domains (e.g., netflix.com) bypasses the VPN.
Applications: All traffic from a specific app (e.g., Spotify) bypasses the VPN.
Local Networks: Traffic to your home or office network bypasses the VPN.
If you experience issues with specific websites or apps, communicate this to your IT department. They can adjust the split exclude configuration to improve your experience.
Privacy: Remember that traffic excluded from the VPN is not encrypted. Be mindful of the sensitivity of data transmitted through these excluded connections.
Security: Only exclude traffic you trust. Avoid excluding financial or other sensitive applications.
Performance: If you're experiencing slow VPN speeds, split exclude can help, but it's not a magic bullet. Other factors, like VPN server load or network congestion, can also contribute to slow speeds.
Contact IT: If you're unsure about any aspect of the split exclude configuration, always consult your IT department. They can provide guidance and ensure your security is maintained.
