WAN & LAN Connectivity
Four 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.
