Robust firewall and VPN to secure business communications

The Zyxel SBG3300-N Series applies ACL rules, Stateful Packet Inspection (SPI), Denial of Service (DoS) and DDoS features for first-line defense against hackers, network intruders and other harmful threats. A configurable DMZ provides more flexible accessibility while preventing external attacks on confidential databases.

The SBG3300-N Series additionally features IPSec VPN which empowers companies to provide secure connections to branch offices, partners, road warriors and telecommuters. They can use L2TP or PPTP VPN to safely access corporate networks without having to install VPN software.

  • Robust firewall and VPN to secure business communications
  • Multi-WAN connectivity with load balancing and failover
  • Comprehensive authentication for safe, efficient management
  • Combo WAN-in-a-box to optimize the CAPEX of FTTH/VDSL2 deployments
  • G. vectoring to maximize effective range for service providers
  • Extreme routing performance to take advantage of FTTx applications
  • Five Gigabit ports and 802.11n for superior LAN networking


Multi-WAN connectivity with load balancing and failover

The Zyxel SBG3300-N Series includes multiple WAN interfaces for DSL, Ethernet and USB 3G/4G adapters to establish WAN backups or load balancing. The WAN backup provides contingency in case the primary line or ISP suffers temporary outage. When the primary line of normal services is restored, all traffic resumes normal activity. This function enables highly reliable connectivity and flexibility in multiple applications.

Comprehensive authentication for safe, efficient management

The Zyxel SBG3300-N Series offers a two-level login mechanism to differentiate user segments. The ISP can also define the policies for the limited accounts to easily manage them with the integrated profile database.

11n for superior performance and coverage

The Zyxel SBG3300-N Series Wireless N VDSL2 Combo WAN Small Business Security Gateway featuring 802.11n technology provides the ultimate solution for exceptional security, speed, and coverage. The SBG3300-N Series offers a Web authentication portal for easy management of Internet access. Multiple SSIDs and guest/limited wireless accounts allow companies to protect sensitive data by separating public Internet access from a company’s private LAN. With the guest SSID feature, it’s easy to share wireless connectivity without compromising security; guests are allowed to access only unsecured data.
