    Hi @Pavel

    We haven’t heard about this before and the symptom sounds strange. Can you private message your configuration to us for checking further?

    I reset device to factory default, restore configuration and no problem detected.

    Hi Pavel yep that's the way. works great.

    I just saw this whilst looking for other stuff.

    I had updated https://businessforum.zyxel.com/discussion/4005/dns-resolution#latest wit the same thing issue

    Zyxel_Jerry this seems to be reproducible ... worth a look by your lads in TaiPei Zyxel.

    FYI: we've had this issue with usg40's usg20vpn's and USG60s since Firmware V4.32 came out. The instability was annoying .

    Only seems to be with routers the have been in production for a few years.

    No issue with new USG20VPNW delayed in Feb this 2020.... however its VTI partner usg20wVPN 2016 regularly locked up such that remote SMB file server req's VTI session from other would fail with DNS failures....

    thanks for your confirmation mate!

    Hi @warwickt

    Can you describe more details about the symptoms?

    Is the issue always happened on the USG20W-VPN 2016, or it happens after upgrade to the latest firmware?

    Hi @warwickt

    Thanks for the detail examination and the findings. Regarding to the problematic device "2016 deployed USG20VPN", Had you ever tried to replace the device with the same model USG20VPN "deployed in late 2018" with totally the same configuration file? Are things getting better after swapping by a new manafactured model?

    If so, can you try to do firmware recovery and db recovery by following procedure on your device (remember to save your configuration file locally rebore doing this). The "FW recovery" and "DB recovery" procedure are the same, the only difference is the uploading file (firmware file: xxx.bin, db file: xxx.db)
