Chapter 1: Introduction
SonicOS Enhanced 2.5
SonicOS Enhanced is the most powerful SonicOS operating system designed for the latest
generation of SonicWALL security appliances. SonicOS Enhanced 2.5 is standard on the SonicWALL
PRO 4060 and PRO 5060 and available as an upgrade on the SonicWALL TZ170 Series, PRO 2040,
and PRO 3060.
What’s New in SonicOS Enhanced 2.5
Built on the SonicOS architecture, this operating system features multiple network interfaces and
zones, WAN ISP failover and load balancing, policy-based NAT, object-based management, a multi-
level administrator GUI, and enhanced VPN functionality. SonicOS Enhanced 2.5 builds on these
features with powerful new capabilities and industry-leading technologies.
• Updated Configuration Wizard: SonicOS Enhanced 2.5 includes an new configuration wizard
that includes three configuration wizards: Setup Wizard, Public Server Wizard, and VPN Policy
Wizard to provide you with a quick, easy, and comprehensive configuration of the SonicWALL
security appliance for common deployment scenarios.
• Enhanced VoIP Support: SonicOS Enhanced 2.5 adds comprehensive support for third-party
VoIP equipment, including products from Cisco, Mitel, Pingtel, Grandstream, Polycom, D-Link,
Pulver, Apple iChat, and softphones from Yahoo, Microsoft, Ubiquity, and OpenPhone. SonicOS
Enhanced 2.5 adds the ability to handle SIP, RTSP, H.323v1, H.323v2, H.323v3, H.323v4, H.323
gatekeepers, and LDAP ILS support. The internal DHCP Server capability in SonicOS Enhanced
2.5 allows Cisco CallManager addressing information into the DHCP scope information, so that
Cisco phones can receive addresses when they issue a DHVCP request on the network.
• Hardware Failover Enhancements: SonicOS Enhanced 2.5 includes a number of useful
enhancements to hardware failover, including the ability to automatically synchronize the firmware
between the Primary and Backup SonicWALL security appliances, and the ability to load new
firmware versions on to both devices simultaneously from the Primary SonicWALL security
appliance. You can also specify logical monitoring addresses for each interface.
• Flexible VPN Termination: SonicOS Enhanced 2.5 includes the ability to terminate incoming
site-to-site VPN connections on any interface. This feature is useful in situations where untrusted
transit networks terminate on internal interfaces; an example of this might be a router sitting on a
DMZ Zone/Interface with an untrusted Frame Relay network connecting the router to a business
partner. Using the flexible VPN termination feature, you are able to run a VPN connection across
the Frame Relay connection and know the Frame Relay provider cannot see the traffic.
