TZ350 - 6.5.4.7-83n - Firewall Access Rule disappears after power loss

Mike_Clement · May 2021

Hi,

We just purchased several new SonicWALL TZ350 firewalls. I updated the firmware to 6.5.4.7-83n and created the attached firewall access rule. The rule allows us to access the TZ350 firewall which is at a remote location through our vpn connection.

The rule works wonderfully, until the TZ350 is powered off. When the device is powered back on, the rule disappears. If I recreate the rule, it works great until the device is powered off again.

This problem is happening on all our TZ350 devices, not just one. It feels like a bug, but support is telling me that even though our SonicWALL has support until August, its only hardware support. Their software isn't covered, which frankly, is a sucky answer. If I go to my supervisor and say that we need to buy support for $132 per device, he's going to say order different devices (non-SonicWALL) in the future which I would prefer not doing.

If anyone has any insight, that would be great!

Thanks,

Mike

You shouldn't have to manually create the rule. Under the advanced tab of the VPN Policy there is a section to allow management through the VPN. Just check the box and it will create the rule automatically.

Hi @MIKE_CLEMENT,

Thank you for reaching out to SonicWall Community. We'll definitely help you with possible solution to your question.

The access rule that you are referring to belongs to firewall's web management access. Any access rules meant for firewall management is auto-created and we don't recommend creating them manually. This is FYI for future reference.

Here we recommend you to delete the manually added access rule and follow the steps listed in the below KB article where a checkbox "Management via this SA" for HTTPS needs to be enabled on the respective VPN policy. This checkbox enable will create an auto access rule from VPN to LAN on the firewall where you perform this function.

Hope this helps.

Please let us know for further questions/clarification.
