Description:
If you apply for multiple IP addresses from your ISP, you can assign these public IP addresses to the ADSL Router and public server, e.g., Web or FTP server. Typically the first IP is network address, the second is used as router IP address and the last one is subnet broadcasting. Other remaining IP addresses can be assigned to PCs on the LAN.
The following example uses the LAN IP address ranging from 10.3.75.49 to 10.3.75.54 and the subnet mask for LAN is 255.255.255.248. The WAN address is 10.3.70.1, and the subnet mask for WAN is 255.255.255.252.
