Interfaces
A RouteFinder needs at least two network interface cards (Interfaces) to secure an internal network (LAN)
from an external network (the Internet). From the Network|Interfaces menu you can define the Local
host, up to three Ethernet NICs, and IP Aliases for the RouteFinder.
The first network card (eth0) is always the interface to the internal network (LAN) and is called the trusted
network.
The second network card (eth1) is the interface to the external network (Internet) and is called the
untrusted network.
The RouteFinder must have at least two network cards to protect separate networks or network segments
from each other. The first network card is always the internal one (usually connected to the local network);
the second network card is always the external one (usually pointing towards the Internet).
