How to Enable and Configure the On-board Firewall

The DV-IP Decoder supports an on-board Firewall to add to the security of the
unit. The Firewall can be enabled and will operate in conjunction with the
security applications that are already present in the network.
This feature ensures that unauthorised users can not gain access to the DV-IP
Decoder and therefore have any affect of the operation of the system. With IP
address and port filtering the firewall has been designed to let the authorised
people access and keep everyone else out.
To configure the firewall functionality:
1. If not already enabled, enable the Firewall function within System -> Advanced Features
and Reset the unit for the settings to take affect
2. Select Network -> Firewall
3. Enable the PING response option by placing a tick in the adjacent box. Disabling this feature
will make the DV-IP Decoder less visible on the network. If disabled the ping command will
cease to work
4. Enter the IP addresses that can have access to the unit, these can be a range of addresses
or a single IP address
If there is a range of address then enter the first IP address in the sequence followed by
/nn where nn is the last IP address in the range. Refer to IP Address and Subnet
Calculation below
5. Enter the subnet of the network, if a subnet has been specified in the IP address then that
will take precedence over this subnet
6. Identify the TCP ports that are enabled and available on the DV-IP Decoder, enter the same
number in the To and From values if a single port is required
Note: If you attempt use a port that is not on the list, even if you have a valid IP address you will not gain
access to the unit.
7. Enter the UDP ports on the system that are available, enter the same number in the To and
From values if a single port is require
Note: If you attempt use a port that is not on the list, even if you have a valid IP address you will not gain
access to the unit.
8. Save the configuration by selecting Save Settings!
