Vigor2820 - Dual WAN, ADSL, LAN 3x 10/100/1000 Base-TX, WAN, USB 2.0, 10 W
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.
The 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.
