DSL port in the WAN IP Address field.
The IP address you assign to VCC1 must not be used by another

Domain names identify organizations on the Internet. Enter the

A domain name server is a network computer responsible for

in the Secondary Nameserver Address field.
The secondary nameserver is consulted when the primary
