failure or other failures
occur.

C. PPP IP extension:
When the integrated
gateway is connected with
a computer, the IP address
obtained through the

can enable the advanced
DMZ. At this time, you
need to enter your DMZ

this IP address as the WAN
IP address and does not
need to obtain it through
the upstream link.
