Users of the public network outside the company can access only the DMZ host. The DMZ may typically also have the company’s Web pages so these could serve the outside world. However, the DMZ provides access to no other company data. In the event that an outside user penetrated the DMZ host’s security, the Web pages might be corrupted, but no other company information would be exposed.

Press NAT/DMZ to setup the parameters.

If you want to enable the NAT/DMZ functions, click Enable. Enable the DMZ host Function uses the IP address assigned to the WAN for enabling DMZ functions for the virtual IP address.

Multi-DMZ:

Some users who have two or more global IP addresses

 

assigned by their ISP can be used as a multi DMZ. The

 

table is for the mapping of global IP address and virtual IP

 

address.

Multi-NAT:

Some of the virtual IP addresses (e.g.: 192.168.1.10

 

~ 192.168.1.50) collectively use two of the global IP

 

addresses (e.g.: 69.210.1.9 and 69.210.1.10). The Multi-

 

NAT table will be setup as;

Virtual Start IP Address:

192.168.1.10

Count:

40

Global Start IP Address:

69.210.1.9

Count:

2

Press Finish to continue.
