Q:What is the maximum number of IP Addresses the NetComm ADSL Modem Router can support?

The NetComm ADSL Modem Router can support up to 253 IP Addresses in the range of 192.168.1.2~192.168.1.254.

Q: Where should the NetComm ADSL Modem Router be installed on the network?

In a typical environment, the NetComm ADSL Modem Router should be installed between the ISP and your LAN. Connect the NetComm ADSL Modem Router to the phone jack which supplies the ADSL signal, and connect your computers to the RJ45 jack on the LAN side.

Q: Does the NetComm ADSL Modem Router support IPX or AppleTalk?

Q: Does the NetComm ADSL Modem Router support 100Mb Ethernet?

Yes, the NetComm ADSL Modem Router supports both 10Mb & 100Mb Ethernet on the LAN side, but only 10Mb on the WAN side.

Q: What is “NAT” and what is it used for?

The Network Address Translation (NAT) Protocol translates multiple IP Addresses on a private LAN into a single public IP Address that is accessible to the Internet. NAT not only provides the basis for multiple IP Address sharing but also provides security, since the multiple IP Addresses of LAN computers are never transmitted directly to the Internet.

Q:How can NetComm ADSL Modem Router share single user account to multiple users?

The NetComm ADSL Modem Router combines the following technologies to enable this function.

NAT (Network address translation): NAT is a technology which can create a private network domain behind a public IP. It is usually used as a firewall. It can also be used when there are not enough IP Addresses.

DHCP (Dynamic host configuration protocol): DHCP is a protocol to assign IP Addresses to internal computers automatically. It can save a lot of IP Address configuration. This protocol is supported by Windows 95/NT, Mac OS, and many other popular OS.

DNS (Domain name service): DNS is a protocol which translates Domain Names to IP addresses that an Internet host can handle. Addressing system using Domain names, like www.yahoo.com, is easier to use than its IP address, 204.71.177.70.
