Address Mapping
Allows one or more public IP addresses to be shared by multiple internal
users.This also hides the internal network for increased privacy and security.
Enter the Public IP address you wish to share into the Global IP field. Enter
a range of internal IPs that will share the global IP into the ‘from’ field.
Virtual Server
If you configure the ADSL Wireless Base Station as a virtual server,remote
users accessing services such as web or FTP at your local site via public IP
addresses can be automatically redirected to local servers configured with
private IP addresses. In other words, depending on the requested service
(TCP/UDP port number), the ADSL Wireless Base Station redirects the
external service request to the appropriate server (located at another
internal IP address).
For example, if you set Type/Public Port to TCP/80 (HTTP or web) and the
Private IP/Port to 192.168.1.2/80, then all HTTP requests from outside
users will be transferred to 192.168.1.2 on port 80.Therefore, by just
entering the IP address provided by the ISP, Internet users can access the
service they need at the local address to which you redirect them.
