    Looking at the Conduit MTCDT-246 Hardware Manual, it says the following:

    E-NET RJ-45 receptacle for standard Ethernet 10/100 Base-T.
    ========================================================================
    Caution: Ethernet ports and command ports are not designed to be connected to a public
    telecommunication network or used outside the building or campus.

    ========================================================================

    What does this mean exactly? The IP67 rated outdoor Conduit is PoE, and the Ethernet port is apparently only used for power, but I don’t understand it in regards to a regular (Blue) Conduit or the Indoor Conduit Access Point. I’ve also seen this warning in the rNet Cell Router maual.

    Hi Chris,

    It is a statement of caution. The Conduit’s/rCell’s Ethernet interface is best used behind a firewall and not placed on the public Internet. On the cellular interface (if enabled), the cellular carrier usually offers a private and a public option. Again, ideally the cellular interface should be on a private network. If the cellular interface is put on a public network, there could be data usage consequences due to infiltration/intrusion attempts.

    Let us know if that helps explain it,
    Darrik

    Yes, thanks! We have a private network, but are interested in going public to enable automatic updates from M-T. Can you restrict incoming packet IPs on a public network?
