OpenVPN: Split or Full Tunnel
When configuring your OpenVPN server on the NG Firewall, you have various options you can specify per each client. A commonly asked question is whether or not you should set the configuration to Full Tunnel or Split Tunnel (setting Full Tunnel to false).
What's the difference between the two?
Split Tunnel refers to having your client only use the configured tunnel to reach network resources when requesting them, and all other traffic will be routed through their gateway from their public IP.
Full Tunnel refers to having all network traffic route through the tunnel.
How do I configure the tunnel type?
This configuration is per group, under Apps > OpenVPN > Server > Groups. and allows you to specify your configuration for either, and then to apply it to your clients during client creation depending on their needs, or the network administrators requirements.
NOTE: You can modify a client's group at anytime to specify whether they are full or split tunnel, but it is recommended to resend the OpenVPN client to the host after any modifications to ensure that they take place.
