Cellular Router Firewall
4.3
Router organisation
The IPL-C router provides two IP interfaces : The ADSL interface (WAN interface) to reach the Internet or a
private service and the LAN interface to connect the machine.
WAN interface :
The IPL-C router provides three WAN interfaces :
the ADSL interface is the main WAN interface; but the Ethernet interface of the RJ45 Nr1, or the WiFi
interface when it is used as a client, can be used as a WAN interface.
Only one interface can be used at the same time (cellular, Ethernet port 1, WiFi).
LAN interface :
The LAN interface consists of Ethernet ports, optionally a WiFi interface when it is used as an access point
and serial interfaces.
Firewall
The firewall filters the IP frames between the ADSL WAN interface or any VPN interface on one hand, and
the LAN interface on the other hand.
