3.1 Basic Configuration The basic configuration contains Internet Port, Local Port and the Wireless LAN configurations. After you have finished setting up the basic items, the gateway will work for most scenarios. 3.1.1 Internet Port The Internet Port section contains information to allow your modem to connect to the Internet. You will need to configure this section with the settings that have been assigned and provided by your ISP.
PPPoE Configuration Most DSL-based ISPs use PPPoE (Point-to-Point Protocol over Ethernet) to establish an Internet connection. If you are connected to the Internet through a DSL line, check with your ISP to see what protocol they use. Host Name/Domain Name. Some ISPs require the host name and domain name as identification. If it is not specified, assign on your own or leave it as blank. User Name, Password, Confirm Password.
Packet Size (MTU). The Maximum Transmission Unit of an IP packet. The default value is 1492 Bytes. If your ISP requires a special value, please select from the pull down menu. The default value will work for most cases. Otherwise, contact your ISP for the MTU value. Disconnect after idle time. The PPPoE connection will be disconnected by the gateway automatically when there is no Internet traffic for the idle time specified. The idle time of “0” means an always-on connection.
Static IP Configuration If you connect to the Internet using a permanent IP address, please select Static IP Configuration from the pull down menu and fill the ISP specified values in the fields. Note: If your ISP requires a PPPoE type connection, you should NOT use " Static IP Config". Host Name/Domain Name. Some ISPs require the host name and domain name as identification. If it is not specified, assign on your own or leave it as blank. IP Address. Enter the IP address of the gateway's Internet port.
PPTP Configuration Some older modems use a PPTP connection instead of PPPoE. This connection uses a PPP session to connect to your ISP. After the connection between the ISP and your modem is established, you are able to use your modem to connect to the Internet. Host Name/Domain Name. Some ISPs required the host name and domain name as identification. If this has not been specified, assign on your own or leave it as blank. User Name, Password, Confirm Password.
Packet Size (MTU). The Maximum Transmission Unit of an IP packet. The default value is 1492 Bytes. If your ISP requires a special value, select this from the pull down menu. The default value will work for most cases. Alternatively, contact your ISP for a specified value. Disconnect after idle time. The PPPoE connection will be disconnected by the gateway automatically when there is no Internet traffic for the idle time specified. An idle time of “0” means an always-on connection.
3.1.2 Local Port Configure your gateway's Local Port IP address here. The Local Port must be a private IP address. (10.x.x.x, 192.x.x.x are reserved for LAN use). Subnet Mask. The subnet mask determines the number of computers that are allowed in this network. A class C network with the subnet mask 255.255.255.0 allows maximum 253 users (the gateway is already using the 192.168.1.1) in your local area network. Usually a class C network is satisfactory for a local network. DHCP server.
WINS Server. The Windows Internet Naming Service (WINS) manages each PC's interaction with the Internet. If you use a WINS server, enter the WINS server's IP Address here. Otherwise, leave it as blank. Static DHCP IP & MAC Address. Click Setup in the Local port configuration page to setup the Static DHCP IP. You can assign a fixed IP address to a DHCP client. Put the PC's IP address and MAC address in the fields and click Add to add it to the list. Use Delete or Delete all to manage the list.

Appendix B: Frequent Asked Questions Q: What is a "dynamic IP address"? A: An IP address from your ISP which is assigned via DHCP and is therefore not guaranteed to remain the same. Some cable modem Internet providers provide IP address assignments which rarely change, but the addresses assigned are still considered to be dynamic, not static. Q: When should I modify the MAC address for global port settings? A: Some ISPs identify their clients by their MAC address and host names.
Q: What's MX (Mail Exchanger)? And why MX? A: The Internet email system for both machines and network connections are prone to error. With this, a chain of email hubs into the email architecture is built. If the "primary" mail host goes down, instead of queuing up the mails in the unreliable host on the Internet, they get sent to the "secondary" or "backup" mail exchanger for delivery, until the primary mail server becomes functional again. In technical terms, such service is called a Backup Mail Exchanger.
Appendix C: Troubleshooting This chapter is intended to help you troubleshoot problems you may encounter while setting up and using the NetComm NB620W. It also describes some common hardware and software problems and gives some suggestions to troubleshoot them.
