Modem Ping timeout error

2 thoughts on “Modem Ping timeout error

  1. Hello everyone,

    I am using Telit GL865 modem. I activate context and get dynamic IP allocation for my modem using at command “AT#SGACT=1,1”.

    In response of this command, I get IP assigned to my modem.

    But now when I connect to my server using AT#SD, the IP of modem I get on my server application is different from the IP address I got in response of “AT#SGACT” command.

    1. How to find the global IP of modem so that i can ping it from any where in the world.

    1. Most probable the mobile device is behind a provider router and getting an internal IP address 10.xx.xx.xx or such. The outside world sees the mobile device traffic with a provider address, NAT being performed between the two. In this case you cannot ping the mobile device  (nor run some kind of server in it) unless special tunnelling is done at provider.
