The Juniper Networks SSG-20-SH is a robust Security Services Gateway designed for network security and connectivity. This modular platform delivers 160 Mbps of stateful firewall traffic and 40 Mbps of IPSec VPN throughput, making it suitable for securing network communications. The SSG 20 is equipped with five on-board 10/100 interfaces and features two I/O expansion slots, supporting various I/O cards such as ADSL2+, T1, E1, ISDN BRI S/T, and V.92 for versatile WAN connectivity options.
سيٽ اپ جون هدايتون
Follow these steps to set up your Juniper Networks SSG-20-SH Security Services Gateway:
- پيڪنگ ۽ چڪاس: Carefully remove the device from its packaging. Inspect the gateway for any visible damage. Ensure all components listed in the packing list are present.
- جسماني جڳهه: Place the SSG-20-SH on a stable, flat surface in a well-ventilated area. Ensure adequate space around the device for proper airflow to prevent overheating.
- پاور ڪنيڪشن: Connect the provided power adapter to the device's power input port and then to a suitable electrical outlet. The power LED (labeled "POWER" on the front panel) should illuminate.
- نيٽ ورڪ ڪنيڪشن:
- Connect your local network devices (computers, switches) to the 10/100 Ethernet interfaces (labeled "FE" or similar) on the front panel.
- For WAN connectivity, utilize the appropriate I/O expansion slots for ADSL2+, T1, E1, ISDN BRI S/T, or V.92 cards as needed. Connect your internet service provider's line to the corresponding port on the installed I/O card.
- The "AUX" and "CONSOLE" ports are typically used for management and initial configuration via a serial connection.
- شروعاتي تشڪيل: Refer to the separate configuration guide for detailed instructions on initial network settings, firewall rules, and VPN setup. This typically involves accessing the device via the console port or a default IP address.

ڊوائيس کي هلائڻ
Once the SSG-20-SH is physically connected and initially configured, it operates as a central point for network security and traffic management. Key operational aspects include:
- فائر وال تحفظ: The device actively inspects network traffic, applying configured security policies to allow or deny connections based on rules. This stateful firewall capability ensures secure communication.
- VPN Services: The SSG-20-SH supports IPSec VPNs, enabling secure, encrypted tunnels for remote access or site-to-site connectivity. This is crucial for protecting sensitive data transmitted over public networks.
- نيٽ ورڪ ايڊريس ترجمو (NAT): It performs NAT to allow multiple devices on a private network to share a single public IP address, conserving IP addresses and adding a layer of security.
- رستو: The gateway functions as a router, directing network traffic between different interfaces and networks based on configured routing tables.
- نگراني جي حيثيت: Observe the front panel LEDs for operational status:
- طاقت: بجلي جي فراهمي جي حالت کي ظاهر ڪري ٿو.
- اسٽيٽس: General device status.
- SYNC (for ADSL/V.92 modules): Indicates synchronization status of the WAN connection.
- TX/RX (for ADSL/V.92 modules): Indicates data transmission and reception activity.
- CD (for V.92 module): Indicates Carrier Detect for dial-up connections.
