DHCP services
3-10 Preliminary January 30, 1998 Pipeline User’s Guide
BOOTP servers in the BOOTP Relay menu does not necessarily determine
which server is tried first.
Note:
Previously, the Pipeline could not enable both BOOTP relay and DHCP
spoofing at the same time because the two functions attempted to respond to the
same packets in different ways. Now, if both features are enabled and no WAN
links are active, the Pipeline performs DHCP spoofing. As soon as the dialed link
is established, the Pipeline stops spoofing and acts as a BOOTP relay agent.
DHCP services
A Pipeline can perform a number of Dynamic Host Configuration Protocol
(DHCP) services, including:
• DHCP Server functions, responding to DHCP requests for up to 43 clients at
any given time. DHCP server responses provide an IP address and subnet
mask. Two address pools of up to 20 IP addresses each can be defined.
Additionally, up to three hosts, identified by their MAC (Ethernet) addresses,
can have an IP address reserved for their exclusive use.
• Managing Plug and Play requests for TCP/IP configuration settings from
computers using Microsoft Windows 95 or Windows NT.
• DHCP Spoofing responses, supplying a temporary IP address for a single
host. The IP address supplied is always one greater than that of the Pipeline.
The IP address is good for only 60 seconds—just long enough to allow a
security-card user to acquire the current password from an ACE or
SAFEWORD server and bring up an authenticated dial-up session. Once the
dial-up session is established, an official IP address can be retrieved from a
remote DHCP or BOOTP server.
How IP addresses are assigned
When a Pipeline is configured to be a DHCP server and it receives a DHCP client
request, it assigns an IP address in one of the following ways:
• When the plug-and-play option is enabled (DHCP PNP Enabled=Yes), the
Pipeline takes its own IP address, increments it by one, and returns it in the
BOOTP reply message along with IP addresses for the Default Gateway and
Domain Name Server. Plug-and-play works with Microsoft Windows 95
