WAN & LAN ConnectivityFour Gigabit Ethernet WAN ports and one SFP slot (for fibre modules or an additional Ethernet module) provide 5 independent WAN ports for either load-balancing or failover applications. Gigabit Ethernet and SFP LAN Interfaces provide high speed connectivity to your LAN. Fibre is of particular use for longer distance deliveries, beyond the range of standard Ethernet, or where copper connections cannot be used. WAN Load-balancing weight or traffic-type rules can be set or on an automatic basis to spread WAN traffic evenly across all interfaces on a best-endeavour basis. Firewall The Vigor 3900's firewall is fully stateful, with a flowtrack mechanism and comprehensive WAN defences, including DoS/DDoS protection and flexible IP packet filtering. On the content side, the Vigor 3900 has several methods of content filtering to control user access to the web to keep their access appropriate, safe and productive. That helps keep your network efficient, your data secure and your online productivity high. QoS Extensive QoS facilities allow for efficient local traffic handling, ensuring that critical traffic is given the appropriate priority and that your network topology handles data in the most efficient way to help avoid congestion and bottlenecks. WAN traffic can be assigned one of 8 different priority levels based on egress or ingress. Bandwidth can be reserved for critical applications and DiffServ codepoint classifying can also be applied. Rules can be based on traffic type, users or IP source/desintations.
