 Site-to-Site VPN connection – Site-to-Site VPN connection is an alternative

WAN infrastructure that is used to connect branch offices, home offices, or

business partners’ sites to all or portions of a company’s network.

 Remote Access VPN – Corporations use VPN to establish secure, end-to-

end private network connections over a public networking infrastructure.

VPN have become the logical solution for remote access connectivity.

Deploying a remote access VPN enables corporations to reduce

communications expenses by leveraging the local dial-up infrastructure of

Internet Service Providers. At the same time, VPNs allow mobile workers,

telecommuters and day extenders to take advantage of broadband

connectivity.

2.4.3 WAN Failover & Load Balancing

WAN Failover and Load Balancing allows you to designate the one of the

assigned interfaces as a backup WAN port. If the primary WAN port is down

and/or unavailable, traffic is only routed through the backup WAN port. This

allows OfficeConnect Gigabit VPN Firewall to maintain a persistent connection

for WAN port traffic by failing over to the backup WAN port.

The primary and secondary WAN ports can also be used in a more dynamic

setup, where the administrator can choose a method of dividing outbound traffic

flows between the two WAN ports. This feature is referred to as load balancing.

2.4.4 QoS and Bandwidth Management

QoS and Bandwidth Management function allows voice and data traffic to flow

through where voice traffic is transmitted in the highest priority. With DiffServ

QoS enabled, it guarantees voice packets to have first priority to pass through a

DiffServ QoS enabled devices such as router or switch.

2.4.5 Virtual LAN Interfaces (VLAN)

The Virtual Local Area Network (VLAN) feature allows OfficeConnect Gigabit

VPN Firewall to be partitioned into non-interacting network domains.
