PLANET IPX-1500 - Manual (Page 36)

The Contrast of Virtual DMZ and Address Mapping
Decision about using Virtual DMZ and Address Mapping is decided by private or public IP which server
uses. If server is public IP, it is better to establish Virtual DMZ framework. If server is private IP and
permit accessing for Internet, address mapping or port mapping is ideal solution. The purpose is not to
change the infrastructure and setting formally.
We suggest that it is better to use Port Mapping or Address Mapping when server needs to provide
accessing for Internet. The reason is the Virtual DMZ framework will occupy more bandwidth and cause
the System loading bigger. See the figure, all traffic will through IPX-1500 when PC in intranet want to
access server, but Address Mapping won’t.
Merely, no matter Internet or intranet accesses server using public IP in Virtual DMZ framework but
Address Mapping is more complicate. Internet needs public IP to access Server when intranet needs
private IP.
Both of them are the method to provide service for user, just according to the convenient you
considerate!
