GB-Ware Firewall Product Guide 36
ment Numbers Authority (IANA) has specified network addresses in
RFC 1918 that are designated exclusively for internal networks.
IANA Private Network IP Address Rules
Quantity of Addresses
Available
Network Class IP Address Range
1 A 10.0.0.0 -
10.255.255.255
16 B 172.16.0.0 -
172.31.255.255
256 C 192.168.0.0 -
192.168.255.255
Note
Because GTA firewalls perform NAT, the IP address and any network
addresses behind the firewall (i.e., attached to, or on the protected
network or PSN) can be unregistered. IANA compliance is largely
a matter of convenience in NATted networks.
9. Gateway/Default Route on External Interface (No DHCP or PPP/
PPPoE/PPTP)
If your external network interface is not using DHCP (which
automatically fetches gateway information), enter a default route
for outbound traffic. Once the IP address, net mask, and device
assignment have been made, the wizard will prompt for the default
route. The wizard attempts to determine the network segment of the
IP address automatically.
10. Password
Assign a password to your firewall (required). Initially, the user ID
and password is set to “gnatbox.” The user ID can be changed
later in Authorization
then Admin Accounts.
Caution
GTA recommends changing the default user ID and password to
prevent unauthorized access. See the GNAT Box System Software
User's Guide for instructions.
10. Saving Your Settings
The summary screen displays all your configuration settings. If you
need to make changes, use the
PREVIOUS
button to move back to
the desired dialog and make corrections. Once you are satisfied
with your settings, select
SAVE
and allow the firewall to boot up.
Initial configuration is now complete.
