User`s guide

This flexible configuration allows each port to use a different type of modem and connection
method. Also, the Internet traffic that is shared between the 8 modems can be pre-determined.
•
Support for all common Connection Methods
All popular DSL, Cable Modems and connection methods are supported. These include - Fixed IP,
Dynamic IP, PPPoE and PPTP.
• Inbound/Outbound Traffic Load Balancing and Failover
There are a variety of load balancing methods that allow administrators to manage the traffic from
LAN or WAN in order to maximize bandwidth - as well as smart health check methods to protect
against connection failure for failover.
•
PPPoE Session Management
Multiple PPPoE sessions are supported and you can choose “mapping” sessions to selected PCs
if desired.
• Multiple IP Address Support
If your ISP allocates you multiple IP addresses, these are also supported and you can “map” IP
addresses to selected PCs if desired.
• Special Application
This feature allows you to use some non-standard applications; for example, where the port
number used for the response is different to the port number used by the sender.
• Virtual Server
This feature allows Internet users to access Internet servers on your LAN. For standard servers
such as Web, FTP or E-Mail servers, only the IP address of the server PC is required. You can
also define your own Server types if required.
• Multiple DMZ
A "DMZ" PC will receive incoming connection requests which would otherwise be blocked. For
each IP address allocated by your ISP, a separate "DMZ" PC can be specified. So if your ISP has
given you multiple IP addresses, you can have multiple “DMZ” PCs. With the Multi-WAN VPN
Link Balancer, each “DMZ” PC has unrestricted 2-way Internet access, providing the ability to run
programs that are otherwise normally incompatible with NAT routers.
• Access Filter
The network Administrator can use the Access Filter to gain fine control over the Internet access
and applications available to LAN users. Ten (10) user groups are available and each group can
be assigned unique access rights.
• Block URL
This feature can be used by the Administrator to block access to undesirable Web sites by LAN
users. You can even assign different settings for different groups of PCs.
• Session Limit
With the Session Limit feature, if the number of new sessions for the system exceeds the
maximum allowance set by the Administrator in the sampling time, any new session in the system
will be dropped.
• System Filter Exception
This feature ensures that every packet with an unrecognized port will be rejected so as to prevent
access to port scanning programs from hackers. However, in some situations this may incur
