- ADSL2/2+, Annex L and Annex M
- 2 ADSL2+ port bonding
- Stateful Packet Inspection
- Anti Denial-of-Service attack and port scanning
- IGMP proxy/snooping for IP multicast
- Port-based VLAN to support triple-play services

ZyXEL P-663H-51 is an all-in-one ADSL2+ gateway for Home, SOHO and SMB applications. Featuring two ADSL2+ WAN ports and four 10/100Mbps Ethernet LAN ports, the P-663H-51 provides SPI (Stateful Packet Inspection), anti-DOS (Denial of Service) and many Firewall security features to protect against network intrusion and attacks.

In addition, advanced features such as IP multicasting, IGMP proxy/snooping, fast leave and IP QoS fulfill the need of triple-play services, while the G.bond-based port bonding feature groups the 2 ADSL2+ physical ports into a logical link. The link not only provides VDSL-equivalent bandwidth with much longer loop length, its load-balance feature between the two ports also makes P-663H-51 the best choice for business and high-end market applications.

Higher-speed Broadband Access
The P-663H-51 has two ADSL2/2+ WAN ports. With the ATM-based multi-paired bonding feature, the two ports can be grouped into a logical link boasting the bandwidth twice as fast as a single ADSL2/2+ port, and the bit rates of each individual port can be freely and independently changed by their respective PHY layer. If one of the member ports fails, the conveyed traffic will be moved to the other port. When the failed port recovers, it will seamlessly return to the logical link and share the transmission/reception of the upper-layer traffic.

Robust, State-of-the-Art IP Security
The P-663H-51 supports state-of-the-art Firewall features, Stateful Packet Inspection, anti-DoS (Denial of Service) and IP/MAC address spoofing protection for basic defense against hackers, network intruders and other hazardous threats.

Sophisticated QoS for Triple-Play Services
The P-663H-51 comes with complete ATM and Ethernet QoS mechanisms, as well as various IP QoS features (Packet classification/Rate Limitation/Queue Scheduling). The seamless QoS-mapping not only allows consistent and appropriate traffic treatment of packets, but also enables fulfillment of triple-play services. The IGMP proxy/snooping and fast leave (v1, v2) features also supports the IP multicasting service easily.
