Know about Knowledge router port mapping or the most important, where we mainly analyzed the specific configuration of the router port mapping, and software support port mapping iis7 server monitoring tool is how to configure them. Implement extranet access network.
If the server computer through the Internet router ADSL + manner, it is necessary to set the router port mapping in response to the router at the server computer. The method may be because the router settings differences in the way the set will be different. But exactly the same.
In one example below describes the WEB server network is 192.168.1.101, administered default router address that is 192.168.0.1. Admin admin account password to log in to the router administered by the interface, click on the router forwarding rules - Virtual Server - add a new entry (Figure). 
Port mapping settings are as follows: Port number fill in 80, if the fill is 80-82 represents the mapped port 80, 81, fill in the IP address within the network WEB server's IP address 192.168.1.101, set protocol to TCP, if port protocol You can set the selected type does not inquire as ALL, on behalf of all (including TCP and UDP), conditions must be set to bear fruit. Common service port number, as a way to help prompt action, unnecessary selected, and then click retained, mapping victory! (Figure) 
hot Mody, support port mapping port mapping software nat123 how to do? nat123 mapped can be applied in any environment, the network application is mapped to external networks. Port mapping settings specific steps: Log software, the main panel / port mapping list / increase port mapping.
Increases edit the map, select the type of application the necessary mapping. Such as the release site, selected 80 sites. Access address corresponding to the network port within the application: the network address and port. Localhost native address format may be applied. External network address Port: expected extranet domain name address and port can access.
