1.2.1 Being a router between two Ethernet interfaces

The ESG-103 connects one Ethernet interface, which is from ADSL/Cable modem's LAN side as its WAN interface. It provides users in its 10/100 base-TX LAN side which can share a single valid IP address. From this kind of configuration, users do not need to apply for a valid IP address for everyone in its LAN side to access Internet. This function can be enabled or disabled. If users apply for many public IP addresses for some purpose, they are also able to use those IP addresses to connect to the Internet.
