How do I open Ports UDP500 UDP1500 and UDP123

I just got a cellspot from T-Mobile and it is telling me to make sure that these ports are open and I do not have any idea how to find them and open them. I would love some help on this.

Thank you!

  • What is the Mfr and model# of the ISP modem the NG router is connected too?

     

    If this device is connected to the Orbi, and you have a modem only infront of the Orbi router, you can use the DMZ for this device On the Orbi. 

    Setup a IP address reservation for this device ON the base router and input this IP address into the DMZ ON the Orbi.

      This is a great solution, as long as the modem is really "only a modem".  On the Orbi web interface, assign the cellspot an IP address on the Advanced tab, Setup, LAN Setup.  It's called "Device Reservation."  Then, input that IP as the "DMZ server", which is on the Advanced tab, Setup, WAN Setup. 

       

      If the modem is actually acting as a router, then it takes more work.

      DMZ is a non-protected destination, so by doing as you suggested all attacks on Orbi will be directed to this device!

      emel1721 Please forward only the ports that you need using the Port Forwarding menu (after resering an address to the device) as follows:

        Plausable however can be used. Something I have used for Voice devices which works for most cases. Haven't seen any attacks on my microcell in the DMZ.
