IP Filtering
The device server has an IP address based filtering feature to prevent unauthorized remote hosts from accessing
device server. The user can allow one of the following scenarios by changing the parameter settings:
•
Only one host of a specific IP address can access the device server
•
Hosts on the a specific subnet can access the device server
•
Any host can access the device server
The user may allow a host or a group of hosts to access the device server. Then the user must enter the IP
address and subnet to be allowed for accessing.
To allow only a specific host to the device server, enter the IP address of the specific host and just give
255.255.255.255 for the subnet. To allow any hosts to the device server, give 0.0.0.0 for both of the IP address
and subnet. Refer to
table 6
for more details.
For example, to allow only a 192.168.1.120 host for accessing, enter the following commands,
1. DHCP mode
