5.5.2 Virtual Server (Port Forwarding) “Virtual Server” can also referred to as “Port Forward” as well and used interchangeably. Resources in the network can be
exposed to the Internet users in a controlled manner including on-line gaming, video conferencing or others via Virtual Server
setup. Don’t repeat ports’ usage to avoid confusion.
Please click on Advance -> Virtual Server and follow the below setting.
Virtual Server : By Default, It’s “Disable”. Check Enable radial button to enable Virtual Server.
Description : Enter appropriate message for resource sharing via Virtual Server.
Private IP : Enter corresponding IP address of internal resource to share.
Protocol Type : Select appropriate sessions, TCP or UDP, from shared host via multiple private ports.
Private Port : A port or a range of ports may be specified as start:end; i.e. port 20:80
Public Port : A port or a range of ports may be specified as start:end; i.e. port 20:80
The Private Port and Public Port can be different. However, total number of ports need to be the same.
Example : Public Port is 11 to 20 and the Private Port can be a 10 ports range.
Click “Add” button to add Virtual Server rule to List. Total of maximum 20 rules are allowed in this List. All rules can be edited
or removed from the List. Click Reboot button to activate your changes. While creating multiple Virtual Server rules, the prior
rules have higher priority. The Virtual server rules have precedence over the DMZ one while both rules exist. Example 1 and
2 demonstrate proper usage of DMZ and Virtual Server rules.
¾ Example 1 : All connections should be redirected to 192.168.2.12 while DMZ is enabled. Since Virtual Server rules
have precedence over the DMZ rule all connections to TCP port 22 will be directed to TCP port 22 of 192.168.2.10
and remaining connections to port TCP 20~80 will be redirected to port TCP 20~80 of 192.168.2.11
DMZ Enabled : 192.168.2.12
Rule Protocol Private IP Private Port Public Port
1 TCP 192.168.2.10 22 22
2 TCP 192.168.2.11 20:80 20:80
