    Possibly the firewall.

    Check the Traffic log on the client. You will need to create a rule to Allow it.

    If you can, post the log here and I can review.

    You might see in the logs about the rule which is blocking it, go to sepm firewall logs and add it.

    What rule should configured for no block this device?

    Possibly the rule "block all other traffic" is blocking the 3g connection - try to create a new allow rule allowing ethernet traffic for this interface.

    Are you running a version of SEP that is lesser than 11.0.7? 

    1) If so kindly upgrade to the latest version that should fix the issue.

    2) If it was an attack check your packet log or traffic log or security log

    3) If you can, post the log here and I can review

    That what I suspected - as for current SEP version - it does not really detects the 3g connections as legitimate - as results all are blocked. The workaround for now as mentioned enabled it explicitely - you can as well check the logs for what exact protocols are being blocked here and the allow only the specific protocols - but I have seen several times the protocols may as well be quite dynamic on 3g connection.

    Future SEP versions should bring some improvements in properly detecting the 3g traffic and allowing it.

    what would be the correct rule to allow automatic connection to modems 3G or 4G? :(

    Hi,

    I'm on SEP12.1Ru2 and still facing this issue. Apparently, it is not fixed on the latest version.

    Latest version is 12.1 RU2 MP1

    Did you check your traffic log?
