VPN drops? Choose what happens next.

A VPN kill switch blocks non-VPN traffic during an interruption, where your device supports it. It is optional: useful when keeping work traffic on your VPN IP matters more than staying online through your normal connection.

You enable this on your device or router. MoreVPN’s server cannot control your device’s fallback connection. Settings vary by app and OS; automatic reconnection and traffic blocking are different features.

Windows · WireGuard

  1. Open WireGuard, select your MoreVPN tunnel and choose Edit.
  2. For a standard full-tunnel profile, check that “Block untunneled traffic” is enabled, then save and activate.
  3. This blocking depends on the profile and applies while the tunnel is active. Deliberately deactivating it restores normal routing; modified or split-tunnel profiles can behave differently.

Android · WireGuard or OpenVPN Connect

  1. In Android Settings, open VPN and the settings for the VPN app you use. Menu names vary by phone.
  2. Enable Always-on VPN and, where available, Block connections without VPN. Always-on by itself is not the blocking option.
  3. With blocking enabled, internet access can remain unavailable until the selected VPN connects. Confirm that your app supports these Android settings.

iPhone & Mac · WireGuard

  1. Edit your tunnel and enable On-Demand for the network types you use, if your app offers it.
  2. On-Demand helps reconnect automatically. It is not a guarantee that all traffic is blocked whenever the tunnel is down.
  3. If strict interruption blocking is essential, contact us with your operating system and app version before relying on this setup.

OpenVPN Connect · Windows, Mac, iOS & Android

  1. Open the OpenVPN Connect menu, then Settings, and enable Seamless Tunnel if available in your version.
  2. This blocks non-VPN traffic while the connection is paused or reconnecting. It does not promise permanent blocking after you deliberately disconnect or quit the app.
  3. On Android, use the system blocking settings above for an always-on setup. Other OpenVPN apps have different controls.

GL.iNet & other routers

  1. Open the router’s VPN Dashboard and review the tunnel’s Kill Switch or Block Non-VPN Traffic options. Labels and scope depend on firmware.
  2. Check which devices and traffic rules are covered. Devices or destinations excluded by routing policies may still use the ordinary connection.
  3. For ASUS, OpenWrt or Linux firewall rules, ask us about your exact model or setup. There is no single setting that applies to every router.

Check your setup before you depend on it

  • Connect and confirm the public IP matches your assigned VPN IP. Check IPv6 as well: some older or IPv4-only profiles may let IPv6 use your normal network. Do not add routes to a configuration blindly; ask support if unsure.
  • If your app supports pausing or a controlled reconnect, check that covered traffic is blocked during that state while the underlying internet is still available. For a controlled interruption test on other clients, ask support for guidance.
  • Turning Wi-Fi off proves only that Wi-Fi is offline. Deliberately disconnecting the VPN may disable its protection, so neither action by itself proves drop protection works. Check sleep/wake and network changes too.

Need to get back online?

Try reconnecting the VPN first. If you deliberately choose ordinary internet access, turn off the relevant blocking setting. On Android, this may mean disabling Block connections without VPN; on a router, review its kill-switch and global blocking rules. Apple On-Demand may also need disabling before a manual disconnect will stay disconnected.

Your normal public IP is visible again when you use an unprotected connection. Re-enable your chosen protection when you are ready to resume VPN-only work.

Ask support about your device

Common questions

Will a kill switch stop my internet?

Yes, when the selected protection is blocking traffic and the VPN is unavailable. That is intentional. Once the VPN reconnects, covered traffic can resume. You can also deliberately disable protection and use your normal connection, which exposes its public IP to the services you access.

Does every MoreVPN configuration include a kill switch?

No. Client-side protection depends on the VPN app, operating system, profile and settings. Server forwarding rules cannot stop your device using another connection after the tunnel drops. Use the instructions for your device and verify its behaviour.

Does L2TP include this protection?

MoreVPN does not supply a built-in L2TP kill-switch setting. If blocking is essential, discuss a suitable client, operating-system or router setup with support. Changing protocol or profile should be reviewed before making changes to an existing service.
