Question about setup virtual server..
X4 zoom ADSL modem&router
WANIP from X4: 64.234.33.45
LAN IP 10.0.0.6
this zoom ADSL modem connnect to D-LINK broadband router
WAN PORT of D-LINK connect to WANPORT of ZOOM X4
WANIP :10.0.0.11
LAN IP: 192.168.0.2
   D-LINK has enable virtual severs to allow port 21..
    from IP 192.168.0.99

>From ZOOM setup virtual server?
Is it correct to setup like this
allow port pubport 21 private port 21 -- addr.
192.168.0.99

Testing the virtual server
ftp://64.234.33.45
entering this addr, lead me to zoom admin config setup..
while I WANT to see ftp page is up...( since it set
anonymous ftp .... )

WHat is missing? 
how to run test correctly?

Cheers.
