Dual-WAN Load Balancing & Backup
As well as the primary ADSL interface, the Vigor 2820 features a
secondary WAN port for Internet access. This is an Ethernet interface
and can connect to a second ADSL modem, cable modem or any other
Ethernet-based Internet feed. The secondary interface can be used
either for WAN-Backup or load balancing.
Robust & Comprehensive Firewall
Security is taken seriously on the Vigor 2820 Series. The firewall
features measures for protection against attacks including DoS (Denial
of Service) attacks, IP-based attacks and access by unauthorized remote
systems. Wireless, Ethernet and VPN are also protected by various
protection systems (see later). A new DrayTek object-based firewall
allows even more setup flexibility than ever, enabling you to create
combinations of users, rules and restrictions to suit
multi-departmental organizations.
Content control features of the firewall allow you to set
restrictions on web site access, blocking download of certain file or
data types, blocking specific web sites, blocking IM/P2P applications
or other potentially harmful or wasteful content. Using DrayTek's new
GlobalView service, you can block whole categories of web sites (e.g.
gambling, adult sites etc.), subject to an annual subscription to the
Globalview server, which is continuously updated with new or changed
site categorizations or sites which have become compromised (such as
infected with Malware).
Dual-WAN Load Balancing & Backup
As well as the primary ADSL interface, the Vigor 2820 features a
secondary WAN port for Internet access. This is an Ethernet interface
and can connect to a second ADSL modem, cable modem or any other
Ethernet-based Internet feed. The secondary interface can be used
either for WAN-Backup or load balancing.
WAN-Backup provides contingency (redundancy) in case of your primary
ADSL line or ISP suffering temporary outage). Internet Traffic will be
temporarily routed via the secondary Internet access. When normal
services is restored to your primary ADSL line, all traffic is switch
back to that.
If you don't have ADSL, the Ethernet WAN port can instead be used as
your primary/only Internet connection (using NAT) so the same router
can be used for either ADSL or Ethernet Internet connections.
The USB port provides an alternative connection method for Internet
backup by connecting to a compatible USB modem (or cellphone) for
access to the high speed 3G cellular networks from UK
providers such as Vodafone, Orange, 3 and T-Mobile. If you don't have
ADSL at all, the USB/3G access method can be used as your primary/only
Internet connection, ideal for temporary locations, mobile applications
or where broadband access is not available. In addition you can instead
connect a compatible analogue modem to use analogue dial-up connections
for failover in the event of your broadband failing. See separates page
for more details on both 3G and analogue dial-up.
On the ISDN-equipped model (Vigor2820VSn) you can instead use ISDN for dial-in or dial-out connectivity and backup.
Note : For WAN failover you can use only one method at a time, e.g. Ethernet, 3G or analogue connections.
