Configuring Network Settings
Note: The internal network range is defined both by the NetDefend fire
IP address and by the subnet mask.
For example, if the NetDefend firewall's internal IP address is 192.168.100.7, and
you set the subnet mask to 255.255.255.0, the network's IP address range will be
192.168.100.1 – 192.168.100.254.
The default internal network range is 192.168.10.*.
