What You Need To Know
Management IP Address
When you first connect a management PC or laptop to a built-in Ethernet port on a
Services Router, the router acts as a DHCP client and attempts to perform an
autoinstallation. If it does not find a DHCP server, the router assigns
as the IP address for port 0. (If you are connected to port 1,
assigned as the IP address. Port 2 and port 3 are assigned
192.168.4.1/24
Because this address is not part of any explicit configuration, it is removed when
you change the configuration in any way. You must configure an IP address for this
LAN port when you commit your initial configuration. (See Step 2. Configuring Basic
Settings with J-Web Quick Configuration" on page 10 or Step 2. Configuring Basic
Settings with the CLI" on page 13.)
J-Web Access
The Web interface to the router—called the J-Web interface—is enabled by default.
To configure the router with the Web interface, you attach a PC or laptop to a built-in
Ethernet port. The examples in this document use the first built-in Gigabit Ethernet
port
See Step 1. Connecting, Logging In, and Starting the J-Web Interface" on page 9.
CLI Console Access
Services Routers are shipped with a console cable and adapter. To configure a Services
Router through the console port with the JUNOS Enhanced Services command-line
interface (CLI), you use a terminal emulation program such as Microsoft Windows
HyperTermimal. (See Step 1. Connecting, Logging In, and Starting the
CLI" on page 12.)
Secure Context and Router Context
You can operate the router either in secure context or router context. These contexts
are meant to be starting points from which you can customize the configuration for
your network requirements. By default, the Services Router operates in secure context.
For information describing how to change contexts, see the JUNOS Enhanced Services
Administration Guide.
The basic configuration for secure context binds the
preconfigured zone called trust. All other interfaces are bound to a preconfigured
untrust zone. The
management access. These services as well as Telnet, HTTPS, and DHCP are
configured as host-inbound services for the
TCP Reset is also enabled. The default policy for the trust zone allows transmission
of traffic from the trust zone to the untrust zone. All traffic within the trust zone is
allowed.
