< Small and Mid-size Business Network Environment >

In a Small and Mid-size Business (SMB) network environment, devices such as switches, hubs, and access points

are commonly used, and Internet connection is usually via an ADSL or a cable modem. WHG303 uses virtual LAN

(VLAN) technology to partition one physical network under its control into nine logical virtual networks, called

Service Zones, including one untagged zone and eight tagged zones. The untagged zone is also referred as the

Default Service Zone in this system, which is always enabled. On the other hand, the other four tagged zones can

be enabled or disabled respectively. By default, port-based configuration is used and all of the four physical LAN

ports are set to use the Default Service Zone.

The figure below demonstrates an example of the SMB network deployed with WHG303. Both LAN and WLAN of

the system can be secured by IPSec VPN. WHG303 will actively establish VPN tunnels while the selected users

are logging in. Not only the traffic within the office network will be protected by IPSec VPN, this VPN module can be

configured to support site-to-site IPSec VPN tunnels across remote branch offices. The same clientless VPN setup

implementation can also be extended to remote users in accessing office network from public Internet via PPTP

VPN tunnels. Once the remote client-to-site PPTP VPN tunnels are established, traveling Employee can connect

back to the office network via reliable, secure connections using their portable devices.
