In other words, the MTX-Tunnel modems connect in client mode, meaning that they do not affect the
NATs nor the majority of Firewalls. The connection is not made directly with with PC, yet using an
intermediary, i.e. using the Titan router’s No-NAT plugin.
On the other hand, your control software will also connect to the Titan’s No-NAT plugin, meaning the
Titan router will act as an intermediary between the PC and the different modems.
We will illustrate this with an example:
In this case, we must configure the GPRS modems (MTX-Tunnel) to work in client mode
(MTX_mode: client) and so that an identificative chain is sent so that the Titan knows which MTX-
Tunnel each connection corresponds to. For example, we can make MTX-Tunnel 1 send “A-000001”
(MTX_IDClient: A-000001) as the identificative chain and MTX-Tunnel devices 2 and 3 will send “A-
000002” and “A-000003” respectively. Each of them must connect to the TCP port 40000 in the Titan
router.
On the other hand, the PC must connect to the Titan’s IP address (for example the local Ethernet
address 192.168.1.2) when it wishes to connect to the MTX-Tunnel 1 modem, as well as the
corresponding TCP port. For example, to connect to the MTX-Tunnel 1 device, the Titan port 30001
will be used.
