7. INITIAL CONNECTION TO THE PRODUCT
7.2 Configuration
When you first receive your firewall, it will run in transparent mode and will have the IP address
10.0.0.254 with a subnetwork mask 255.0.0.0.
These parameters do not match your network configuration, but they are however necessary for
the preconfiguration phase.
If you do not know what these parameters mean, we strongly advise that you read up on TCP/IP in
order to understand how to configure your NETASQ firewall.
These are the intervals defined by the different classes of IP address:
Class
IP address range
A
0.0.0.0 to 127.255.255.255
B
128.0.0.0 to 191.255.255.255
C
192.0.0.0 to 223.255.255.255
D
224.0.0.0 to 239.255.255.255
E
240.0.0.0 to 247.255.255.255
Some parts of these address ranges are reserved for private networks:
Class
Reserved IP address ranges
A
10.0.0.0 to 10.255.255.255
B
172.16.0.0 to 172.31.255.255
C
192.168.0.0 to 192.168.255.255
Preconfiguring from a Windows workstation is the method that we recommend, which is what we
will be using for our illustrations. The workstation can either be di
rectly linked to the firewall’s
internal interface, or connected to the local network, itself linked to the firewall’s internal interface.
For a direct connection of the workstation to the firewall, use the crossover Ethernet cable, which
has been delivered with the product.
WARNING
Please refer to section
5.4: Connecting to the network
To connect to the firewall, you need to use a workstation with an IP address in the same
subnetwork as the firewall. We suggest that you use the address 10.0.0.1 and the subnetwork
address 255.0.0.0.
