You can obtain your IP address from the IANA, from an ISP or have it assigned by a private network. If you
belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the
Internet addresses for your local networks. On the other hand, if you are part of a much larger organization,
you should consult your network administrator for the appropriate IP addresses.
Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address assignment,
please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466,
Guidelines for Management of IP Address Space.
6.3.1 WAN MAC Address
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is assigned at
the factory and consists of six pairs of hexadecimal characters, for example, 00:A0:C5:00:00:02.
You can configure the WAN port's MAC address by either using the factory default or cloning the MAC
address from a computer on your LAN. Once it is successfully configured, the address will be copied to the
"rom" file (configuration file). It will not change unless you change the setting or upload a different "rom"
file.
ZyXEL recommends you clone the MAC address from a computer on your LAN
even if your ISP does not require MAC address authentication.
Your ZyWALL’s WAN Port is set at half-duplex mode as most cable/DSL modems only support half-duplex
mode. Make sure your modem is in half-duplex mode. Your ZyWALL supports full duplex mode on the
LAN side.
