IPsec traffic will go through this link. However, should unforeseen problems (e.g.,unplugged cables or ISP

GRETunnel
Generic Routing Encapsulation (GRE) is a tunneling protocol that can encapsulate a wide variety of
network layer protocols inside virtual point-to-point links over an Internet Protocol network. A GRE tunnel
is similar to IPSec or PepVPN.
To configure a GRE Tunnel, navigate to Network > VPN > GRE Tunnel.
Click the New Profile button to create new GRE tunnel profiles that establish tunnel connections to remote
tunnel endpoints via available WAN connections. To edit the profiles, click on its associated connection
name in the leftmost column.
