Specifications

Data over DSL Software

>Multiprotocol encapsulation over ATM per RFC 1483

>Classic IP-over-ATM per RFC 2225

>ATM/DSL management features (OAM f4/F5 and ILMI)

Bridging and Routing

>Bridging based on IEEE 802.1d protocol, RIP version 2.0 routing per RFC 2453

> Support for multicast	unicast
filters based on	and
destination MAC

>Support for multicast traffic through IGMP proxy

Optional VPN Software

>Supports three types of VPN: L2TP (RFC 2661), PPTP (RFC 2637), IPSec (RFC 2401, 2406)

>Provides software encryption libraries for SHA-1, MD5, 3DES and AES, and APIs for easy integration with third- party encryption software libraries

>Provides well-defined interfaces for using a hardware encryption processor for improved VPN performance

>Supports both manual and dynamic configuration of IPSec policies (using IKE)

>Supports MSCHAPv2 (RFC 2759), MPPE (RFC 3078) with RC4/ARC4 encryption

Address Management

>Supports WAN interface IP address acquisition through either DHCP (RFC 2131, 2132) or PPPoE

>Facilitates static IP addressing of the DSL router WAN interface

>Supports dynamic and static addressing (mixed-mode addressing) of home network devices

>Supports host name based resolution

in the home	through dynamic
DNS (RFC	1035, 2136, 2535)

>Synchronized address management ensures address change

notifications between various modules, which makes in-home device address configuration changes transparent to users

>PPP/PPPoE support (PPP: RFC

1661, PPPoE: RFC 2516, PAP: RFC

1334, CHAP: RFC 1994)

NAT and Firewall

>Robust NAT implementation per RFC 1631 and RFC 2993

>NAT supports both pass through and port forwarding

>Built-in NAT ALGs for PING, FTP, L2TP, PPTP, IPSec, SMTP, RTSP, RTP, H.323 applications, plus APIs to develop additional ALGs

>Robust implementation of stateful Layer 2 IP packet filter, provides protection against attacks: IP Spoof, SYN flood, IP Smurf, LAND, Ping of Death, UDP Echo Storm, Reassembly

>Packet filter rules are configurable through HTML UI, and all events related to packet filter policy violations or suspicious activities are appropriately logged

Remote Management

>SNMPv1/v2/v3 based management (RFC 1157, 2271-2274)t

>Supports the following protocol MIBs:

•MIB2–RFC 1213

•NAT MIB–working group draft

•RIP MIB–RFC 1724

•DHCP MIB–working group draft

>User-initiated software/firmware upgrades

Local Management

>Provides a small-footprint HTTP1.1 Web-server from Go-ahead.com

>Extensive HTML user interface for DSL router management and configuration by end user

>Parental protection URL filter through HTTP1.1 proxy

>RADIUS client-based user authentication (RFC 2865) for controlling access to DSL router administration UI

>Restoration of factory default settings in case of incorrect user configurations
