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.
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
