The NAT (port mapping) NAT (port mapping) nat in the ADSL routing is network address translation is to translate the public network IP into private addresses, also called port mapping or port forwarding. Use routing means that ADSL has a dynamic or fixed public network IP, ADSL direct Pick on the HUB or switch, all computer sharing internet. At this time, the external address of the ADSL has only one, such as 61.177. *. *. The internal IP is a human set, such as the ADSL set to 192.168.0.1, the following computer is set to 192.168.0. * (* Represents 1, 2, 3, ...). How to implement NAT features? There is a virtual server setting in the general router. To do the following settings: Enter the "Virtual Server", select: TCP, IP Address: 192.168.16.x (LAN IP address of the Mail Server), Select: TCP, IP Address: The other method of POP3), 6080 (Webmail) is open host. Open Host (DMZ Host) is aimed at the IP address, the function of the firewall is removed, and the IP address of the local area network directly maps to the external IP, and the opening of the host (DMZ) is used, and the port does not have to be much. This way only supports an internal computer. Several ADSL MODEM port mapping practices are set by Mail Server in internal PC 192.168.1.2, and the SMTP default port of Mail Server is 25.
