Cradlepoint CBA750 4.2 IP Pass-Thru

CRADLEPOINT CBA750 | USER MANUAL Firmware ver. 1.9.0

IP Passthru allows a client co nnected to the private network to be

configured automatically with the public IP address acquired from the

ISP. The configuration is done by passing the client a DHCP lease

with the public IP address when the WAN becomes connected. If

there is more than one client connected to the private LAN, the user

can b ind the MAC address of a particular client to IP Passthru in

order to ensure that client a lways receives the correct DHCP lease.

Otherwise, the IP Passthru will pick the first device connected to the

LAN to use IP Passthru.

4.2.1 IP Passthru Mode

IP Passthru Mode. Selecting Bind MAC Automatically will allow IP

Passthru to automatically try to setup the client's connection to the

Internet. This setting is the default setting, and should work in most

cases. However, if there is more than one client connected to the

private network, then selecting Bind MAC Manually will configure

the router to only allow one particular client.

Client MAC Address. If you would like IP Passthru to be restricted to

a particular client, enable this option and enter the client‟s MAC

address into the association field. T he router will grab the MAC

address of the client connected to it during configuration. If this isn't

the right address, enter the MAC of the correct device.

Ignore Switch Position. The CBA750 has a Configuration Switch on the outside of the router that can be set to Passthru

Mode o r Configuration Mode. Selecting Ignore Switch Position disables this switch so that you control this setting

through the administration pages only. If you select Ignore Switch Position, you must then also choose either:

 Force Passthru Mode

 Force Configuration Mode
