[ALERT8867] Potential loss of network connectivity after upgrading ESET Cyber Security from version 6 to version 9

• An issue in the configuration migration tool that causes all firewall rules to be deleted in ESET Cyber Security version 9 after upgrading from version 6 builds.
• After upgrading from ESET Cyber Security  version 6, the firewall in ESET Cyber Security  version 9 is disabled by default.
• The issue only occurs after manually enabling the firewall in ESET Cyber Security  version 9 following the upgrade.
• Upgrades from ESET Cyber Security  version 7 or later are not affected.

Solution

• ESET Cyber Security firewall version 9 after upgrading from version 6, we recommend waiting for the upcoming hotfix (version 9 build), which will resolve this issue.
• Already upgraded from version 6 to version 9:
  • Do not enable the firewall until you have reconfigured the required firewall rules.
  • You can restore at least the default firewall rules for
    • Business version ESET Endpoint Security by running the following command in the terminal:
      echo "{\"method\" : \"_CE.rpc_api.screen_values_set_todefault\", \"params\" : {\"paths\" : [\"Settings.Firewall.Rules\"]}}" | sudo /Applications/ESET\ Endpoint\ Security.app/Contents/MacOS/cfg --json-rpc /dev/stdin
      command required admin privileges
    • Home version ESET Cyber Security  
      • by opening Firewall Setup and clicking the “Default” button in the lower-left corner.
      • or running the following command in the terminal:
        echo "{\"method\" : \"_CE.rpc_api.screen_values_set_todefault\", \"params\" : {\"paths\" : [\"Settings.Firewall.Rules\"]}}" | sudo /Applications/ESET\ Cyber\ Security.app/Contents/MacOS/cfg --json-rpc /dev/stdin
        command required admin privilegs
• If you plan to use version 9 without the product firewall, you can safely upgrade from version 6 to the released build of version 9.
