Configuration
ipFireGuard Firewall
sits "in between" your Internet connection and your
internal network(s) with all traffic with external sources
or destinations monitored by the firewall.
| ipFireGuard
defines three (3) types of network interfaces:- |
| Red |
The red
network is the Internet or other untrusted network. ipFireGuard's
primary purpose is to protect the GREEN and ORANGE networks
and their computers from traffic originating on the RED
network. Your current connection method and hardware (modem,
isdn, cable/xdsl) is used to connect to
this network. |
| Green |
This interface
only connects to the computer(s) that ipFireGuard
is protecting. It is presumed to be local. Traffic to
it is routed though an Ethernet NIC (network interface
card) on the ipFireGuard
firewall. |
| Orange |
This optional
network allows you to place publicly accessible servers
on a separate network. Computers on this network cannot
get to the GREEN network, except through tightly controlled
"DMZ pinholes". Traffic to this network is routed
through an Ethernet NIC. The ORANGE NIC must be different
from the GREEN NIC. |
Acting as the gateway/web proxy for your
internal network only traffic/communications initiated by
you is allowed to pass. All external access is denied unless
you have set up the rules/privileges to allow selected locations
or individuals to enter. This could be in the case of a secure
VPN (virtual private network)
(as shown above).
