Example:
If you would like to remotely access your routers' Web/HTTP interface all the time, you would need to
enable port number 80 (Web/HTTP) and map it to the Router's LAN IP Address. All incoming HTTP
requests on the WAN network will then be forwarded to the router's IP address of 192.168.1.254.
port number 80 is already a predefined rule, click Helper in the Application section.
rules window will pop and you can select HTTP_Sever.
Application: HTTP_Sever
Time Schedule: Always On
Protocol: tcp
External Port: 80-80
Redirect Port: 80-80
IP Address: 192.168.1.254

Using port forwarding has security implications, since outside users will be able
to connect to Computers on your network. For this reason you are advised to
add specific Virtual Server entries only for the ports that your application
actually requires, instead of using the DMZ function. Using the DMZ function
will result in all connection attempts from the WAN network having access to
the public IP specified in the DMZ config section.
If you have disabled the NAT option in the WAN-ISP section, the Virtual Server
function will not work.
If the DHCP server option is enabled, you have to be very careful when
assigning the IP addresses of virtual servers so that you avoid conflicting IP
addresses. The easiest method of configuring Virtual Servers is to manually
Attention
assign static IP address to each virtual server Computer, with an address that
does not fall into the range of IP addresses that are to be issued by the DHCP
server. These manually configured IP addresses MUST still be in the same
subnet as the router.
