1.
From the Web Management Interface, click on Configuration , then DHCP . The DHCP Settings screen
appears:
Nomadix’ patented Dynamic Address Translation (DAT) functionality is automatically
configured to facilitate “plug-and-play” access to subscribers who are misconfigured with
static (permanent) IP addresses, or subscribers that do not have DHCP capability on their
computers. DAT allows all users to obtain network access, regardless of their computer’s
network settings.
2. DHCP Services
is enabled by default. Do not disable it unless you want to lose all your DHCP services.
By default, the Access Gateway is configured to act as its own DHCP server and the relay
feature is disabled. If you want the Access Gateway to act as its own DHCP server, do not
enable the relay. Go directly to Step 8.
3.
To route DHCP through an external server, enable the DHCP Relay .
4. If you enabled the DHCP Relay feature, you must assign a valid DHCP Server IP address (the default
is 0.0.0.0) and a valid DHCP Relay Agent IP address.
The DHCP Relay Agent allows the Access Gateway to request a specific range of IP addresses from
different IP pools from the DHCP Server. Leaving these fields blank forces the system to use the IP
pool that contains IP addresses that are on the same subnet as the Access Gateway.
You must disable the DHCP server before enabling the DHCP relay. Both features cannot
be enabled concurrently.
If the DHCP Relay Agent IP address is set for an address that is already used or
the IP address of the server, the other system will get an IP conflict and will not
have Internet access.
5. If desired, enable Relay Agent Information (option 82).
The DHCP Relay Agent Information Option (option 82) allows the NSE to add information to a relayed
DHCP request. This information identifies the origin of the request.
