Port Redirection
Figure 4- 11. Port Redirection Menu
The Port Redirection feature of the Router is used in conjunction with NAT or IP Masquerading to improve
security and efficiency. Port redirection can be used to direct potentially hazardous packets to a proxy server
outside your firewall. For example, you can configure the Router to direct HTTP packets to a designated HTTP
server in the DMZ. Other common applications might include directing incoming SMTP packets to an Email
server for data scrutiny and improved network efficiency.
Port Redirection can be used to redirect TCP or UDP packets to a specified port and a specified IP address on
your local network. You can define a set of instructions for a specific incoming port or for a range of incoming
ports. Each instruction set or rule is indexed and can be modified or deleted later as needed.
The user changeable variables available for Port Redirection are listed in the table below.
