About the SRX220 Services Gateway
The Juniper Networks SRX220 Services Gateway offers complete functionality and
flexibility for delivering secure, reliable data over IP, along with multiple interfaces that
support WAN and LAN connectivity and Power over Ethernet (PoE).
The device provides Internet Protocol Security (IPsec), virtual private network (VPN),
and firewall services for small and medium-sized companies and enterprise branch and
remote offices.
SRX220 Services Gateway Models
The SRX220 Services Gateway is available in two models, which are described in Table
3 on page 3.

Accessing the SRX220 Services Gateway
Two user interfaces are available for monitoring, configuring, troubleshooting, and
managing the SRX220 Services Gateway:
•J-Web interface: Web-based graphical interface that allows you to operate a services
gateway without commands. The J-Web interface provides access to all Junos
functionality and features.
•Junos OS command-line interface (CLI): Juniper Networks command shell that runs
on top of a UNIX-based operating system kernel. The CLI is a straightforward command
interface. On a single line, you type commands that are executed when you press the
Enter key. The CLI provides command Help and command completion.
