Controlling Access by IP Address
By default, all IP addresses are granted access to DMZ Gateway. You can grant access to only one
specific IP address or a range of IP addresses, or deny access to one specific address or a range of
addresses. You can define up to 100 IP address masks.
For example, if you want to allow only 192.168.174.159 and block every other IP address, click
Denied access , click Add , then type
192.168.174.159
in the IP mask box. This will deny access
to all IP addresses except 192.168.174.159.
To grant/deny access by IP Address

2. In the Configuration pane, click the Access tab. The exception list appears.
3. The Access tab displays the IP addresses that are granted or denied access. By default, all IP
addresses are granted access, and no exceptions are displayed in the list.
