Downgrading firmware may cause firewall rules to revert to defaults


Applies To:

GRV-EPIC-PR1

Versions Affected:

1.2.0 to 1.3.2

Resolved In Version:

1.4.0


Symptoms:

In the following combination of circumstances, the firewall rules will revert to factory defaults:

  • You are downgrading firmware versions.
  • Before starting the firmware update, you select the option to automatically back up and restore firewall rules.
  • The firewall rules in the firmware version you're downgrading from contain ports that were reserved in the default rule set of the firmware version you're downgrading to.

Workaround:

If you are starting from 1.4.0 or newer and you are downgrading to 1.3.2 or earlier, remove UDP and TCP rules for ports 8502, 22006, and 22007.

Resolution:
