Cellular Bridge
Cellular Bridge creates a bridge between Eth2 and the terminal's cellular
interface for UDP and TCP traffic. The IP address of the connected device should
be set to be the same as the IP address for data connections allocated by the
SIM card as shown in the "Cell/Client IP" sub-menu.
Note that there is potentially a security risk of unauthorized access to the device connected to Eth2 and to
minimize this risk the SIM card should use a private APN (see Cellular Settings section below), such as that
provided by the AddSecure Link service.
6.5.1.1 DHCPSRV or Fixed
Click on «DHCPSRV» if you want the terminal to assign the IP address to the device attached to Eth 2
automatically.
6.5.1.2 Cell/Client IP
This is the IP address that must be assigned to the device attached to Eth 2 and called from the cellular
network when a remote connection to this device is required. This address is the address the cellular
network assigns to the SIM card and cannot be changed.
6.5.1.3 Subnet mask
This setting is fixed and is the subnet mask that should be set on the device attached to Eth 2.
6.5.1.4 Gateway
This is the gateway IP address that should be set on the device attached to Eth 2. It is preset and fixed and is
derived from the cell/client IP address.
Cellular Routed
Cellular Routed routes UDP and TCP traffic between Eth2 and the terminal's
cellular interface. The terminal converts the IP address of traffic received on
the cellular interface to an address configured on the terminal for the device
connected to Eth2, and vice-versa.
The default for Cellular Routed mode is set to the Forwarded IP address (i.e., the address of the attached
device) of 192.168.1.1 and the Gateway IP address (i.e., the address of the Eth2 connection on the terminal)
set to 192.168.1.254. The DHCP server is on by default.
Note that there is potentially a security risk of unauthorized access to the device connected to Eth2 and to
minimize this risk the SIM card should use a private APN (see Cellular Settings section below), such as that
provided by the AddSecure Link service.
6.5.2.1 DHCPSRV or Fixed
Click on «DHCPSRV» if you want the terminal to assign the IP address to the device attached to Eth 2
automatically.
6.5.2.2 Eth 2 IP/Gateway
This is the gateway IP address that should be set on the device attached to Eth 2.
6.5.2.3 Subnet mask
This setting is fixed and is the subnet mask that should be set on the device attached to Eth 2.
