   • Connect your LAN (internal network) devices to the available GigE ports.
5. Pristup početnoj konfiguraciji:
   • For initial configuration, connect a console cable (RJ-45 to DB-9) from your management workstation to the console port on the SRX210.
   • Konfigurišite softver za emulaciju terminala (npr. PuTTY, Tera Term) sa sljedećim postavkama: 9600 bauda, ​​8 podatkovnih bitova, bez parnosti, 1 stop bit, bez kontrole protoka.
   • Log in using default credentials (if applicable) or follow the Junos OS initial setup wizard.

Refer to the Juniper Networks documentation for specific port assignments and initial configuration procedures for your network environment.

3. Operating the SRX210 Services Gateway

The SRX210 Services Gateway operates on Juniper Networks' Junos OS, a command-line interface (CLI) based operating system. Basic operation involves configuring security policies, routing, and network services.

• Junos OS CLI: Access the device via the console port or SSH for configuration and monitoring. Familiarize yourself with basic Junos OS commands for configuration mode, operational mode, and commit operations.
• Sigurnosne politike: Configure firewall filters and security policies to control traffic flow between different network zones (e.g., trust, untrust, DMZ).
• Prevođenje mrežnih adresa (NAT): Implement NAT to allow internal network devices to access the internet using a limited number of public IP addresses.
• VPN konfiguracija: Set up Virtual Private Networks (VPNs) for secure remote access or site-to-site connectivity. The SRX210 supports IPsec VPNs.
• Routing and Switching: Configure static routes, dynamic routing protocols (e.g., OSPF, BGP), and VLANs as required by your network topology.
• Nadgledanje: Use operational commands to monitor system status, interface statistics, security logs, and active sessions.

For detailed instructions on specific configurations, consult the Juniper Networks Junos OS documentation available on their official website.
