Configuring a DHCP Server
By default, the Safe@Office appliance operates as a DHCP (Dynamic Host Configuration
Protocol) server. This allows the Safe@Office appliance to automatically configure all the
devices on your network with their network configuration details.
Note: The DHCP server only serves computers that are configured to obtain an IP
address automatically. If a computer is not configured to obtain an IP address
automatically, it is recommended to assign it an IP address outside of the DHCP
address range. However, if you do assign the computer an IP address within the
DHCP address range, the DHCP server will detect this and will not assign this IP
address to another computer.
If you already have a DHCP server in your internal network, and you want to use it instead
of the Safe@Office DHCP server, you must disable the Safe@Office DHCP server, since
you cannot have two DHCP servers or relays on the same network segment.
If you want to use a DHCP server on the Internet or via a VPN, instead of the Safe@Office
DHCP server, you can configure DHCP relay. When in DHCP relay mode, the
Safe@Office appliance relays information from the desired DHCP server to the devices on
your network.
Note: You can perform DHCP reservation using network objects. For information, see
Using Network Objects on page 227.
Note: The following DHCP server configurations are not available for the OfficeMode
network:
• Enabling and disabling the Safe@Office DHCP Server
• Setting the DHCP range manually
•
