2. Before upgrading:

• Back up your current configuration (System Maintenance > Config Backup).
• Use the ".ALL" file for upgrading to preserve your settings.
• If upgrading from an older version, review the release notes for specific instructions.

3. If remote access is enabled:

• Disable it unless absolutely necessary.
• Use an access control list (ACL) and enable 2FA if possible.
• For unpatched routers, disable both remote access (admin) and SSL VPN.
