   Probably. What feeds the R6120? Apparently, it's some kind of
(modem+)router, and cascading two routers leads to problems like this,
often described as "double NAT".

   The usual solutions to these problems involve disabling the router
features on one of the two devices. One way would be to put the
(unspecified) (modem+)router into modem-only or "bridge" mode. Another
would be to reconfigure the R6120 as a wireless access point.

   Visit http://netgear.com/support , put in your model number, and look
for Documentation. In the User Manual, look for "Use the Router as a
WiFi Access Point Only" (page 113). Or, in the web interface:
      ADVANCED > Advanced Setup > Wireless AP

   Which method to use depends on which router has the better feature
set.

  Thanks for helping. Yes , the router is connected to a fiber optics modem. so it is the modem that give 100.100.xxx.xxx to the router ? as the Internet service need to dial up, i think i cannot use it as AP. i think i will have to use filezilla server and port forwarding , am I correct ?

       Not a very detailed description of anything.

       Yes.

       What does "dial up" mean here? What is "it"?

       If you use the R6120 as a wireless access point, then I don't know if
    its ReadySHARE features (FTP/HTTP access to USB storage) will work.
    
       In any case, if the fiber modem+router is the router with the public
    IP address, then that router is the one which must do the port
    forwarding. If you leave the R6120 as a full-function router (behind
    the fiber modem+router), then you would want the fiber modem+router to
    forward the FTP and HTTP[S] ports to the R6120. Devices which are
    connected to the R6120 would still have "double NAT", but you may not
    care.
    
       I know nothing about your fiber modem+router, so I can't say if it
    can do port forwarding. If it has a bridge mode, then that might solve
    all your problems, because that would make the R6120 the router with the
    public IP address.
