Welcome to DNSFilter! We're thrilled to help you get started with protecting your network from threats.

Before configuring your DNSFilter setup, we recommend checking your environment for any existing conflicts or settings that can cause issues during the initial installation, especially if deploying our Roaming Client. We know there's no one-size-fits-all deployment, but completing this checkup can help avoid common errors or delays.  

Update firewall settings. Update firewall settings to allow EDNS traffic (follow these guides for Windows or macOS devices) and to prevent end-user circumvention.

Review VPN settings. Determine the best configuration for your environment to support uninterrupted internet connectivity.

Disable IPv6. Local DNS servers listening in IPv6 mode do not work with our Roaming Client at this time. Our team is working on an update to enhance this experience, and until this update is complete we recommend keeping the default IPv4 mode in place.

Review our Local Resolver Support guide to understand what resolvers recent Roaming Client versions can support. 

Cleanup Stale DNS Resolvers. If you're coming from another DNS filtering service, make sure there aren't any stale DNS resolvers in your DHCP or Static network settings. This includes roaming agents that weren't uninstalled.

Because our Roaming Client stores previous OS settings, failure to "clean" the environment can result in restoring those stale name servers if/when our agent is not active.
