SIP-2

COMMUNICATION NODE TYPE SIP-2

56/145

USER GUIDE - Rev. 3 (January 2018)

There are two types of unsafe (unencrypted) tunnels: IPIP and GRE. The difference

between them is that IPIP tunnels can only encapsulate IPv4unicast traffic, whereas GRE

tunnels admit multicast traffic.

To guarantee privacy and safety, the data circulating on the tunnel can be encrypted

through the IPSec cipher protocol. It can be configured through the

VPN

menu.

FIGURE 26

Tunnel

submenu of the

WAN

The configuration parameters are:

•

Tunnel ID.

This establishes the name of the virtual tunnel-like device.

•

Type.

This establishes the desired tunnel type; GRE or IPIP.

•

Tunnel IP

. This establishes the IP address associated with the virtual tunnel

device, whose identity is the value of the

Tunnel ID

parameter. The address must

be the host address, but it admits the inclusion of the associated net mask and also

its configuration in an indirect form, through the equipment device identifier, in

which case the IP address configured in this interface is assigned with a host mask.

•

Tunnel Source

. This establishes the local interface through which the tunnel traffic

will be routed. In the case of WAN interfaces, it may be

cell0-0

(identifies SIM A) or

cell0-1

(identifies SIM B). Otherwise, it will be a virtual network identifier from one

of the VLANs in the equipment.

•

Remote GW

. This establishes the IP address of the equipment at the other end of

the tunnel, that is to say, the terminator.

•

Remote network

. The remote subnetwork connected to the point at the end of the

tunnel (Remote GW) whose traffic passes through the tunnel. If

any

is selected, all

traffic not accessible locally or based on specific rules will be sent through the

tunnel.
