Network Interface | Tunnels | GRE Client for VPN
GRE (Generic Routing Encapsulation) tunnel is one of the solutions for tunneling private network over
the TCP/IP connection (e.g. PPTP, L2TP, PPPoE). GRE tunnel does not use encryption. It only
encapsulates data and sends it over the Internet. So the administrator should take care that no
unencrypted private information is going through the GRE tunnel. By default there is no GRE tunnels
on the AC:
