VPN force-all
GRE tunnelling supports “VPN force-all,” which forces all traffic coming from the LAN onto the GRE tunnel. You
accomplish this by setting the default route to go through the GRE tunnel. A secondary host route where all
tunneled GRE packets route to the actual WAN interface can be configured as a static route when required.
The following table outlines various force-all configurations for different networking scenarios; all other options
can safely use their default values:
