The ProLiant DL320 Security Server

• A computer on the internal network

The DHCP server can be installed on the ProLiant DL320 Security Server if there are no other server

computers on the internal network where a DHCP server can be installed. Installing the DHCP server on

the ProLiant DL320 Security Server is a second choice because VPN clients cannot obtain an IP address

from the DHCP server on the ProLiant DL320 Security Server itself. Configure a static address pool of IP

addresses to assign to VPN clients when the DHCP server is installed on the ProLiant DL320 Security

Server. Another reason to keep the DHCP server off the firewall is to reduce the number of applications

running on the firewall, all of which create potential portals for attack.

Placing the DHCP server on a computer located on the internal network enables the VPN clients to obtain

IP addressing information from the DHCP server. In addition, the ProLiant DL320 Security Server can

automatically define the VPN client's network based on the IP addresses it obtains from the DHCP server.

Another advantage is that the DHCP Relay Agent routing service can optionally be installed on the

ProLiant DL320 Security Server and DHCP options can be assigned to the VPN client's network, such as a

primary domain name.
