MSM7xx Controllers Configuration Guide v6.4.0

3. Under Addresses, define the following:
• Start / End: Specify the starting and ending IP addresses that define the range of addresses
the DHCP server can assign to client stations. The address assigned to the controller is
automatically excluded from the range.
• Gateway: Specify the IP address of the default gateway the controller will assign to DHCP
users. In most cases you will specify the IP address of the controller LAN port as the
Gateway.
• DNS servers to assign to client stations: This is always the IP address of the LAN port.
4. Under Settings, define the following:
• Domain name: Specify the domain name the controller will return to DHCP users. Typically,
this will be your corporate domain name.
The host name in the currently installed SSL certificate is automatically assigned as the
domain name of the controller. The factory default SSL certificate that is installed on the
controller has the host name wireless.hp.internal.
You do not have to add this name to your server for it to be resolved. The controller
intercepts all DNS requests it receives. It resolves any request that matches the certificate
host name by returning the IP address assigned to the Internet port. All other DNS requests
are forwarded to the appropriate DNS servers as configured on the Controller >> Network
> DNS page.
To summarize, this means that by default, any DNS request by a user that matches
wireless.hp.internal will return the IP address of the LAN port (Access network on the
MSM720).
• Lease time: Specify the lease time (in seconds) that the controller will assign to all assigned
addresses. As long as a user remains connected, their address is automatically renewed
when the lease time expires. If a user disconnects without releasing their address, then
the address remains reserved until the lease time expires. If you have a small address
pool and a large user turnover, setting a long lease time may cause you to run out of
addresses even though they are not really in use.
