    Hi @SistemistaDaRidere. Please, don't make also the community laugh. Would you please share more info about your USG20W-VPN?
  • Thank you for the reply, sure i would share some more:

    All interfaces disabled except for Lan1 - Wan - WanPPP
    Trunk: llf - WanPPP active, Wan passive
    One vpn ssl configured, disconnected by now
    Some nats configured and related security policies (same nats and policies for wanppp and wan interfaces, tried disabling the wan ones but no results)
    Ap profile running at 2.4GHz in WPA2-mix security

    Any other thing missing?

  • sorry, i didn't mention that all nats are in NO loopback mode

    Are you using any of the value added licenses from Zyxel? (policy compliance, Antivirus, Antispam, Content filtering)
  • just Firmware Upgrade Service

    I home that soon some of representative could show up and support more. My "fear" was the use of the content filtering (and quite a load of traffic) but it was only my personal assumption.

    IDK the function of the process qmi-proxy, looking for a search over Internet didn't provide any useful hint/explanation.

    I believe qmi-proxy is related to LTE interface. Do you have a LTE/cellular modem attached to the USG?
