GRE Tunnel

Generic Routing Encapsulation (GRE) is one of the available tunneling mechanisms which uses an IP as the
transport protocol and carries many different passenger protocols. The tunnels behave as virtual point-to-point
links that have two endpoints identified by the tunnel source and tunnel destination addresses at each endpoint.
To create and configure a secure GRE tunnel, follow these steps:
Step 1
Click VPN > GRE tunnel.
Step 2 Click Add to add a new configuration or Edit or Delete to edit or delete an existing one.
Step 3
In the Add/ Edit a GRE tunnel section, configure the following:
Interface Name
Enable
Tunnel Source
Tunnel Destination
IP Address of GRE tunnel
Subnet Mask
MTU
Step 4 Click Apply.

VPN Passthrough

The VPN Passthrough allows VPN clients to pass through this router and connect to a VPN endpoint. It is
enabled by default.
To configure the VPN Passthrough, follow these steps:
Step 1
Select VPN > VPN Passthrough.
Step 2 To enable the passthroughs, check On for each of the approved protocols:
• IPSec Passthrough – Internet Protocol Security (IPSec) is a suite of protocols used to implement secure exchange
of packets at the IP layer.
The MPPE encrypts data in PPP-based dial-up connections or PPTP VPN connections.
128-bit key MPPE encryption schemes are supported. Select the MPPE encryption (None
or 128 bits) from the drop-down list.
Enter the name of the interface to connect to tunnel.
Check to enable the interface.
Select the tunnel source from the drop-down list.
Enter the tunnel destination (Static IP or FQDN).
Enter the IP address of the GRE tunnel which carries the transport protocol.
Enter the subnet mask of the GRE tunnel.
Enter the maximum transmission unit (MTU).
