Besides those two services depending on what you purchase, there is also two
options to organize the internal domestic LAN:
“Multiple stations”, this operation mode allows to connect many computers
and share the external single internet connection. This requires the use of a
special feature in the router called “NAT” (Network Address Translation) that
manages the translation of the internal IP addresses of the different devices into
the single public IP of your Internet connection. In this operation mode the
internal devices are not visible or reachable from Internet so you increase the
LAN security. The disadvantage is that there may be special applications that
can’t work under this configuration (though very odd) and will require the use of
the “single station” operation mode.
”Single station”, this operation mode only one equipment can connect to
internet at a time. The advantage in this mode is that the connected equipment
is directly connected to internet. So there is no restriction to the kind of
applications that can be used. On the other hand, the disadvantage of being
directly connected: the internal equipment will be visible and reachable from
everywhere out in the internet and can be (and most probably will be) target of
hacker programs. It is highly recommended to use good firewall software in
“single station” mode. The X7968 built in firewall can also be used for this task.

“Documentación del fabricante” folder.
Based on above operational modes and the IP services hired, there are four
different scenarios that require different router configurations. The specific
router settings required for these four scenarios will be shown next:
