The Vigor2820 is an ADSL2+ router with 2nd Ethernet WAN. This 2nd WAN can connect to DSL / Cable modem or fiber media converter for policy-based load-balance, fail-over and BoD; it also features advanced bandwidth control mechanisms such as IP-layer QoS, NAT Session Limitation, Bandwidth Borrowed, etc., to allow easy, flexible and reliable access control and bandwidth management.

With hardware-based implementation of the VPN protocol, the Vigor2820 supports up to 32 VPN tunnels using advanced protocols such as IPSec/PPTP/L2TP/L2TP over IPSec with AES/DES/3DES for encryption and MD5/SHA-1 for authentication.

This SPI firewall uses Object-based design to make setting of firewall policies easy. The CSM feature allows more precise and efficient access control for URL/Web content filtering, IM and P2P applications.
