ufficiently wide bandwidth is always needed for cyber café, medium office, or Internet on-line game room, but it will cost more to use a specific Internet connection with the wide bandwidth. Now AirLive presents you the IGR series product - AirLive IGR-2500, which allows you to achieve the same bandwidth requirement at a lower cost by combining several internet connections with narrower bandwidths. It has 4 WAN ports and one changeable DMZ port, so the total useful WAN ports can be up to 5. With a high performance CPU, IGR-2500 can handle around 300 ~ 400 computers and provide stable and versatile connecting quality as well. With load balance functions, there is no more worry for the Internet connection needed.

Generally, the Multi-WAN devices provide only Outbound Load Balance, but AirLive IGR-2500 also features Inbound Load Balance that redistributes access traffic from Internet users to LAN server via different WAN connections-to increase the usable bandwidth and to avoid Internet traffic jam.

AirLive presents you two different models of Multi-WAN Internet Gateway, IGR-1500 and IGR-2500. Both devices feature multiple WAN connection and load balance function. Each of the two models also has its own characteristics as shown:

Multiple WAN Connections

Up to 5 WAN connections are supported with IGR-2500. As a result, the network constructer can easily combine many ADSL or cable connections to increase the total bandwidth.

Outbound Load Balance

The Outbound Load Balance function can increase the useful bandwidth and prevent network bottleneck. With various types of the balance mode (Session, Weighted Round Robin, and Dynamic Traffic) to choose from, the user can enlarge the useful bandwidth quite easily without expensive charge.

Inbound Load Balance
Inbound Load Balance feature not only redistributes the incoming packets evenly to LAN server but also provides the fail-over function to guarantee the connection working smoothly. With different types of the balance mode (Session and Weighted Round Robin) to choose from, the user can select the
most suitable one for current environment.

Ultra Smart Sharing
Ultra Smart Sharing function can prevent disconnection from a banking system or an Internet on-line game server-due to one single user attempting to access those systems with dual IP addresses.

QoS
IGR-2500 can manage the bandwidth by services and IP addresses-to guarantee the access bandwidth and keep the service server working properly.
 
Intrusion Security
Embedded with protected mechanisms to secure internal client, including Local IP Filtering, Intrusion Security, DoS, URL Filtering, and Session Limit.
 
ARP Protection
The ARP table records the MAC address with a corresponding IP address. If the router's ARP table is destroyed by virus, LAN users will not be able to access Internet properly. The AirLive IGR-2500 ARP protection feature would restore the ARP table back to normal and keep the Internet connection working smoothly.
