Internet Sharing Features 
• 
Shared Broadband Internet Access
 
LAN users can access the Internet through the Syswan Duolinks SW24 Series Load Balancer by sharing 
one (1) or two (2) Broadband modems and connections. 
• 
Supports all common Connection Methods
  
All popular DSL, Cable Modems and connection methods are supported, including Fixed IP, Dynamic IP, 
PPPoE, and PPTP. 
•  PPPoE Session Management  
Multiple PPPoE sessions are supported. You can choose to “map” sessions to individual PCs. 
•  Multiple IP Address Support  
If your ISP allocates multiple IP addresses, you can “map” up to eight (8) public IP addresses to individual 
PCs. 
•  Special
 Applications
 
This feature allows you to use some non-standard applications, where the port number used for the 
response is different to the port number used by the sender.  
• 
Virtual Servers
 
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. Optionally, you can also 
define you own Server types. 
• 
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. Each “DMZ” PC has unrestricted 2-way Internet 
access, providing the ability to run programs that are otherwise incompatible with NAT routers (like the 
Syswan Duolinks SW24 Series Load Balancer). 
• 
Access Filter
  
The Network Administrator can use the Access Filter to gain fine control over Internet access and 
applications available to LAN users. Five (5) user groups are available, and each group can have different 
access rights. 
•  Built-in DNS server - Duolinks SW24 VPN Plus only 
This feature is available only on the Syswan Duolinks SW24 VPN Plus Load Balancer. 
The Duolinks SW24 VPN Plus has a built in DNS server. This feature allows you to setup DNS and to 
provide Inbound and outbound load balancing features to users. 
 URL Filter
 
This feature blocks LAN users from accessing undesirable web sites. You can even have different 
settings for different groups of PCs. 
• 
Session Limit
 
With the Session Limit feature, if the numbers of new sessions for the system exceeds the maximum 
sampling time, any new session in the system will be dropped.
