Initial setup considerations 11

Internal IP address

The IP address assigned to the internal interface of the ProLiant DL320 Security Server must be a valid IP

address for the network to which the firewall is directly connected. This address must meet the following

requirements:

• The internal IP address must be on the same network ID as other computers connected to the same

network segment.

• The internal IP address must not already be in use on the network.

• The internal IP address, in most cases, is statically assigned. Do not use DHCP to assign an address

to the internal interface unless you have a specific requirement to do so. This configuration helps

prevent name resolution issues for the firewall and web proxy clients.

Examples of network IDs commonly used on LANs include:

• 192.168.1.0 with a subnet mask of 255.255.255.0

• 10.1.0.0 with a subnet mask of 255.255.0.0

• 172.16.0.0 with a subnet mask of 255.255.0

NOTE: The server uses a default internal IP address of 192.168.2.1. Change the IP address during setup to

meet the unique addressing requirements of the network.

For example, consider the network depicted in the following figure. All of the computers on the network

have the same subnet mask, which is 255.255.255.0. The three computers on the LAN have the IP

addresses:

• 192.168.2.2

• 192.168.2.3

• 192.168.2.4
