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.

DHCP Configuration

The DHCP is the default service for the Internet Port section. This means that you will get the IP address from the ISP automatically. Choose this type of Protocol for Optus Cable.

Host Name/Domain Name. Some cable ISPs require the host name and domain name as identification. You may have to check with your ISP to see if your broadband Internet service has been configured with a host and domain name. In most cases, you can assign your own or leave it blank and it will work.

Use Static DNS. If you want to use your own DNS instead of the one provided by your ISP, check this box, and type the IP address of the DNS in the field. (At least one in the primary field.)

MAC address. Some ISPs allow you to connect to them with a specified MAC address only. You can enter the MAC address manually or copy it from a PC which is attached to the Local Port. Simply type in its IP address and the gateway will copy the MAC address from that PC. The gateway comes with the factory default MAC address. You do not need to change the default value if the ISP is not checking the MAC address of your Internet Port.

NB620W Super-G Wireless Broadband Gateway User Guide YML725 Rev1 20 www.netcomm.com.au

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. Enter your username, password and confirm again in the fields for the login to the ISP.

Service Name. Enter the ISP specified service name or assign one of your own if the Service Name is not specified.

YML725 Rev1 NB620W Super-G Wireless Broadband Gateway User Guide www.netcomm.com.au 21

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. The default value is “0” minute.

Enable Unnumbered PPP Connection. Check this box and enter the IP address of the unnumbered connection. Contact your ISP if you are unsure if this feature is required for your PPPoE connection.

Use Static DNS. If you want to use your own DNS instead of the one provided by your ISP, click the checkbox and type the IP address of the DNS in the field. (At least one for the primary field.)

NB620W Super-G Wireless Broadband Gateway User Guide YML725 Rev1 22 www.netcomm.com.au

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. Please use the ISP specified address.

Subnet mask. Enter the subnet mask supplied by your ISP.

Gateway. Your ISP will assign a gateway address for you. If you can not find one, please

contact your ISP.

Primary DNS. Enter the domain name server of the ISP.

Secondary DNS. The back up domain name server can be left blank if necessary.

MAC address. Some ISPs allow you to connect to them with a specified MAC address only.

You can enter the MAC address manually or copy it from a PC which is attached to the Local Port. Simply type in its IP address and the gateway will copy the MAC address from that PC. The gateway comes with the factory default MAC address. You do not need to change the default value if the ISP is not checking the MAC address of your Internet Port.

YML725 Rev1 NB620W Super-G Wireless Broadband Gateway User Guide www.netcomm.com.au 23

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. Enter your username, password and confirm again in the fields for the login to the ISP.

Server IP. Your modem's IP address. You must set your computer to be the same domain as your modem (For example, if your modem's IP address is 192.168.0.1 and the subnet mask is

255.255.255.0, your PC must be configured as 192.168.0.x, where the x is from 2 to 254, and

the subnet mask should be same as the modem's 255.255.255.0). You will be able to access your modem. Use "ping <your modem's IP>" in the command line of your PC to test your configuration.. If you don't know the modem's IP address, please refer to the modem's manual or consult your ISP.
