application. List all existing PCs connecting to the network. You may assign a PC with

IP address and MAC from this list.

Example:

If you like to remote accessing your Router through the Web/HTTP at all time, you would need to enable

port number 80 (Web/HTTP) and map to Router’s IP Address. Then all incoming HTTP requests from

you (Remote side) will be forwarded to the Router with IP address of 192.168.1.254. Since port number

80 has already been predefined, next to the Application click Helper. A list of predefined rules window

will pop and 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

Delete: Click it to delete this virtual server application.

If you have disabled the NAT option in the WAN-ISP section, the Virtual Serve

function will hence be invalid.

If the DHCP server option is enabled, you have to be very careful in assigning the IP

addresses of the virtual servers in order to avoid conflicts. The easiest way o

configuring Virtual Servers is to manually assign static IP address to each virtual

server PC, with an address that does not fall into the range of IP addresses that are

to be issued by the DHCP server. You can configure the virtual server IP address

manually, but it must still be in the same subnet as the router.

Using port forwarding does have security implications, as outside users will be able to

connect to PCs on your network. For this reason you are advised to use specific

Virtual Server entries just for the ports your application requires, instead of using

DMZ. As doing so will result in all connections from the WAN attempt to access to

your public IP of the DMZ PC specified.
