Core Features & Functionality
1. Advanced Network Protection
The SSG140 supports an advanced set of network protection features, including security zones, virtual routers, and VLANs. This allows administrators to segment the network into distinct, secure domains with unique security policies for each.
2. Comprehensive Routing Engine
Beyond security, the SSG140 is a powerful router supporting:
-
Protocols: BGP, OSPF, RIP v1/v2, and RIPng (IPv6).
-
Encapsulations: PPP, MLPPP, Frame Relay, and HDLC.
-
IPv6 Support: Dual-stack IPv4/IPv6 firewall and VPN, with IPv4-to-IPv6 translations.
3. High Availability (HA)
To ensure maximum uptime for mission-critical applications, the platform supports:
-
Active/Active and Active/Passive modes.
-
Session Synchronization for both firewall and VPN to prevent drops during failover.
-
Device and Link Failure Detection with automated configuration synchronization.
4. Integrated Management
The device is easily managed through multiple interfaces:
-
WebUI: Graphical interface for easy configuration and monitoring.
-
CLI: Full Command Line Interface via console, Telnet, or SSH.
-
Centralized Management: Compatible with enterprise-level network and security managers.
Related FAQs
1. Can the SSG140 ports be used as a switch?
Yes. You can use Bridge Groups (bgroup) to group multiple physical Ethernet ports into a single broadcast domain. This allows the ports to function as a high-speed local switch while sharing security policies.
2. Does the SSG140 support Power over Ethernet (PoE)?
No, the SSG140 does not have built-in PoE support. To power devices like IP phones or wireless access points, you will need to use external power injectors or connect them to a separate PoE-capable switch.
3. What is the difference between the “SH” and “SB” models?
The SH (Secure High) version typically comes with higher memory (512MB) and support for a larger number of concurrent sessions and VPN tunnels compared to the SB (Secure Base) version. Most modern deployments utilize the high-memory version to support UTM features.
4. Can I use the SSG140 to connect to a Fiber optic network?
Yes, but this requires an optional SFP PIM module. Once the SFP PIM is installed in one of the expansion slots, you can use various SFP transceivers to connect to fiber-based WAN or LAN links.
5. Is the SSG140 still compatible with newer IPv6 networks?
Yes. The SSG140 running ScreenOS 6.2 or later provides robust IPv6 support, including IPv6 firewalling, VPN, and dual-stack (IPv4/IPv6) routing, making it viable for modern network transitions.
