Virtual Server
Use the Virtual Server function when you want different servers/clients in your LAN to handle
different service/Internet application type (e.g. Email, FTP, Web server etc.) from the Internet.
Computers use numbers called port numbers to recognize a particular service/Internet
application type. The Virtual Server allows you to re-direct a particular service port number
(from the Internet/WAN Port) to a particular LAN private IP address and its service port number.
Enable Virtual Server: Enable Virtual Server.
Local IP: This is the LAN client/host IP address that the Public Port number packet will be
sent to.
Local Port: This is the port number (of the above Private IP host) that the below Public
Port number will be changed to when the packet enters your LAN (to the LAN
Server/Client IP).
Type: Select the port number protocol type (TCP, UDP or both). If you are unsure, then
leave it
to the default “both” setting.
Public Port: Enter the service (service/Internet application) port number from the
Internet that will be re-directed to the above Private IP address host in your LAN
Comment: The description of this setting.

ALG
An application gateway is an application program that runs on the router. When a client
program establishes a connection to a destination service, it connects to an application
gateway, or proxy. The client then negotiates with the proxy server in order to communicate
with the destination service. In effect, the proxy establishes the connection with the destination
behind the firewall and acts on behalf of the client, hiding and protecting individual computers
on the network behind the firewall.
This creates two connections: one between the client and the proxy server and one between
the proxy server and the destination. Once connected, the proxy makes all packet-forwarding
decisions. Since all communication is conducted through the proxy server, computers behind
the firewall are protected.
You can select the pre-
programmed ALG’s on this page.
