Address allocation

Default
By default, the CN3000 assigns addresses as follows:
addresses
Addressing The following addressing options are available.
options
Wireless/LAN ports
A unique feature of the CN3000 is its ability to support connections from client stations
that have a preconfigured static IP address. This means that customers with static IPs
will not have to switch their configuration to DHCP to connect with the public access
interface.
DHCP server
By default, the CN3000 operates as a DHCP server on both the LAN and wireless ports.
These servers are fully configurable on the Network > Address allocation page
DHCP relay agent
The CN3000 provides a flexible DHCP relay implementation. It can listen for requests
on the LAN or wireless ports (or both) and forward them to the:
• Internet port
• IPSec tunnel operating on Internet port
This option is fully configurable on the Network > Address allocation page.
Internet port
Addressing options for the Internet port include: DHCP client, PPPoE client, static, and
none. To set these options, open the Network > Ports > Internet port page.

Host name

The host name in the currently installed SSL certificate is automatically assigned as the
domain name of the CN3000. The factory default SSL certificate that is installed on the
CN3000 has the host name wireless.colubris.com.
You do not have to add this name to your DNS server for it to be resolved. The CN3000
intercepts all DNS requests it receives on the wireless or LAN ports. It resolves any
request that matches the certificate host name by returning the IP address assigned to
the wireless port. All other DNS requests are forwarded to the appropriate DNS servers
as configured on the Network > DNS page.
To summarize, this means that by default, any DNS request by a client station on the
wireless or LAN ports that matches wireless.colubris.com will return the IP address of
the CN3000's wireless port.
