The port redirection can only apply to incoming traffic. The server users inside the LAN can
not access public IP address of the server. The correct route is to access the server using the
local private IP address of the server, or you should set up an alias in a Windows hosts file.
Please only redirect the ports you know you have to forward rather than forward all ports.
Otherwise, you will compromise the firewall-type security initially deployed by the NAT
facility.
To use this function, please go to NAT page and choose Port Redirection web page. The
Port Redirection Table provides 10 port-mapping entries for the internal hosts.
Service Name Enter the description of the specific network service.
Protocol Select the transport layer protocol (TCP or UDP).
Public Port Specify which port can be redirected to the specified Private IP and
Port of the internal host.
