2-2 WAN
The Broadband Router supports the following types of Internet
connections: Dynamic IP Address, Static IP Address, PPPoE, and PPTP.
2-2-1 Dynamic IP
The Host Name is optional, but may be required by some Service
Providers. The default MAC address is set to the WAN's physical interface
on the Broadband Router. If the Service Provider requires the MAC
address, type it in. Click the "Clone MAC Address" button to copy the
MAC address of the Network Interface Card installed in the PC. The WAN
MAC address will be replaced by this MAC address.
If your ISP is BigPond (Australia), check the Enable box.
