•
Not all wireless networks offer "public" IP addresses that are remotely accessible; some are firewall
protected to allow access from either the same IP pool only or restricted IP addresses. Contact your
wireless network provider or administrator to determine what options are available.
Some device management options can work with dynamic/non-routable IP addresses.
•
Some networks will force device IP addresses to change at regular intervals. Without proper
configuration, this could cause a remote device to become inaccessible if the device IP address is
not known. The CTM-200 can be configured to generate a report when the IP address of the device
changes.
•
Incorrectly configuring the device could cause the device to become inaccessible, use caution when
issuing commands via any remote mechanism.
