Ip Filtering - Sena NEMO10 User Manual

3.4 IP Filtering

The NEMO10 has an IP address based filtering feature to prevent unauthorized remote hosts from
accessing NEMO10. 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 NEMO10
- Hosts on the a specific subnet can access the NEMO10
- Any host can access the NEMO10
The user may allow a host or a group of hosts to access the NEMO10. Then the user must enter
the IP address and subnet to be allowed for accessing.
To allow only a specific host to the NEMO10, enter the IP address of the specific host and just
give 255.255.255.255 for the subnet. To allow any hosts to the NEMO10, give 0.0.0.0 for both of the
IP address and subnet. Please refer to Table 3-2 for more details.
Allowable Hosts
192.168.1.120
192.168.1.1 ~ 192.168.1.254
192.168.0.1 ~ 192.168.255.254
192.168.1.1 ~ 192.168.1.126
192.168.1.129 ~ 192.168.1.254
For example, to allow only a 192.168.1.120 host for accessing, enter the following commands,
1. DHCP mode
> set ip dhcp 192.168.1.120 255.255.255.255
OK
> save

2. Static IP mode (ip : 192.168.161.5 , subnet : 255.255.0.0 , gateway :192.168.1.1)
> set ip static 192.168.161.5 255.255.0.0 192.168.1.1 192.168.1.120 255.255.255.255
