Overview

Twingate is designed to work seamlessly alongside most networking and security applications. However, some VPN, DNS filtering, and security software may conflict with Twingate due to how they modify network settings. This article outlines known incompatibilities and potential solutions.

Known Incompatibilities

VPN, DNS Filtering, and Internet Security Software

Since Twingate operates at the network level, it may conflict with third-party VPNs, network filtering, and DNS filtering applications. Issues commonly arise when multiple applications attempt to:

If you experience connectivity issues, temporarily disabling or uninstalling these applications may help determine if they are interfering with Twingate.

DNS IP Conflict within the 100.96/12 CGNAT Range

Twingate uses IP addresses within the 100.96/12 CGNAT range to facilitate secure communication between the Client, Connector, and Resources. If your local network or DNS settings include IPs within this same range, conflicts may occur, preventing proper connectivity.

Troubleshooting

If you are experiencing connectivity issues and have VPN, DNS filtering, or security software installed, even if it is not actively running, we recommend the following steps:

  1. Temporarily uninstall the software to see if it resolves the issue.
  2. If the issue is resolved, consider the following workarounds instead of uninstalling the software:
    • Enable bypass/compatibility mode for VPN, ZTNA, or security software that filters network traffic.
    • Add DNS exclusions for your Twingate Resources and *.twingate.com.
    • For antivirus (AV) or endpoint detection and response (EDR) software, create exceptions for*.twingate.com.

⚠ Note: Some security software continues intercepting network traffic even when “disabled.” If exclusions do not resolve the issue, a full uninstall may be necessary.
