Juniper Networks SSG 20 Hostname and Domain Name, Default Route, Management Interface Address

SSG 20 Hardware Installation and Configuration Guide

Hostname and Domain Name

The domain name defines the network or subnetwork that the device belongs to, while the hostname refers to a specific device. The hostname and domain name together uniquely identify the device in the network.

To configure the hostname and domain name on a device, use the WebUI or CLI as follows:

WebUI

Network > DNS > Host: Enter the following, then click Apply:

Host Name: name

Domain Name: name

CLI

set hostname name set domain name save

Default Route

The default route is a static route used to direct packets addressed to networks that are not explicitly listed in the routing table. If a packet arrives at the device with an address for which the device does not have routing information, the device sends the packet to the destination specified by the default route.

To configure the default route on the device, use the WebUI or CLI as follows:

WebUI

Network > Routing > Destination > New (trust-vr): Enter the following, then click OK:

IP Address/Netmask: 0.0.0.0/0.0.0.0

Next Hop

Gateway: (select)

Interface: ethernet0/2 (select)

Gateway IP Address: ip_addr

CLI

set route 0.0.0.0/0 interface ethernet0/2 gateway ip_addr save

Management Interface Address

The Trust interface has the default IP address 192.168.1.1/24 and is configured for management services. If you connect the 0/2 — 0/4 ports on the device to a workstation, you can configure the device from a workstation in the 192.168.1.1/24 subnetwork using a management service such as Telnet.

You can change the default IP address on the Trust interface. For example, you might want to change the interface to match IP addresses that already exist on your LAN.
