Now you can enter the IP address(es) of your remote DHCP ser ver(s), such as might be located in your
company’s corporate headquar ters. Each time you enter an IP address and press Return, an additional field
appears. You can enter up to four DHCP ser ver addresses.
In the example above, DHCP requests from clients on the LAN will be relayed to the DHCP ser vers at IP
addresses 10.1.1.1, 20.1.1.1, 30.1.1.1, and 40.1.1.1.
Note: The remote DHCP ser ver(s) to which the Netopia Router is relaying DHCP requests must be capable of
ser vicing relayed requests. Not all DHCP ser vers suppor t this feature. For example, the DHCP ser ver in the
Netopia Router does
not .
The DHCP ser ver(s) to which the Netopia Router is relaying DHCP requests must be configured with one or more
address pools that are within the Netopia Router’s primar y Ethernet LAN subnet. (There is no mechanism for
DHCP clients to receive an address on a secondar y subnet via a relayed DHCP request.)
Connection Profiles
Since you will probably only have a single connection to your ISP over the DSL link, you may not need to create
multiple connection profiles. Additional profiles may be useful for creating VPNs.
Connection Profiles define the line and networking protocols necessar y for the gateway to make a remote
connection. A connection profile is like an address book entr y describing how the gateway is to get to a remote
site, or how to recognize and authenticate a remote user connecting to the gateway. To create a new
Connection Profile, you navigate to the WAN Configuration screen from the Main Menu, and select
Add
Connection Profile .
