Default Gateway/Peer Subnet:
You can choose “Default Gateway” option
or “Peer Subnet” option here. When “Default Gateway” is chosen, all traffic
from Intranet of Business Security Gateway goes over this GRE tunnel if
these packets don’t match the Peer Subnet of other GRE tunnels. There is
only one GRE tunnel to own the “Default Gateway” property. However, when
“Peer Subnet” is chosen, peer subnet parameter needs to be filled and it
should be the LAN subnet of remote GRE server. If an Intranet packet wants
to go to this peer subnet, the GRE tunnel will be established automatically.
