1.2. Interfaces and Ports
This section is an overview of the NetWall 100 Series product's external connectivity options.
Figure 1.2. NetWall 100 Series Interfaces and Ports
Note: The meaning of the terms "Front" and "Back"
The term "Front" will be used in this guide to refer to the side of the 100 Series that has
the Ethernet ports and the term "Back" to the side that has the status lights.
The NetWall 100 Series features a number of connection ports on the front panel:
•
4 x RJ45 Gigabit Ethernet interfaces
These have the logical cOS Core interface names WAN1, LAN1, WAN2 and LAN2. These
names are written above each interface on the NetWall 100 Series casing.
The LAN1 interface is used for initial management connection. The WAN1 is normally used
for the first connection to the public Internet.
In the default cOS Core configuration, the LAN1 interface of the NetWall 100 Series has an
IPv4 DHCP server enabled on it so it will automatically hand out IP addresses belonging to
the default management network to a connecting client. In addition, both the WAN1 and
WAN2 interfaces have an IPv4 DHCP client enabled so that they can automatically be
assigned an IP address if either or both are connected to an ISP (dual connection can provide
redundancy).
The default cOS Core configuration contains a predefined IP rule set that allows clients on the
LAN1 interface to immediately access the Internet via either WAN1 or WAN2. If both
interfaces provide Internet access,
WAN1
takes precedence because its
all-nets
route has a
lower metric.
The default cOS Core configuration is discussed further in
Section 4.1, “The NetWall 100 Series
.
•
An RJ45 RS-232 console port
This port is used for direct access to the cOS Core
Boot Menu
and the cOS Core
Command Line
Interface
(CLI). Connecting to this port is described in
Section 3.4, “Local Console Port
Note: The two USB Type A ports are not currently used
