  • Before upgrading to 4.4.3, please upgrade to 4.3.2.7 or after to avoid configuration compatibility first.

Security / TOTP / Port Knocking

  • Improved: Allow the Port Redirection/Open Ports/Firewall via Source IP using Domain Name.
  • Improved: Improve Internet access stability with enhanced DPDK Anti-DoS mechanisms, including: bypassing ICMP packets, automatically adding DNS server IPs to the whitelist, and supporting the whitelists configured on the Firewall DDoS Setup page.

  • Corrected: An issue while viewing the dashboard, the router was busy due to a high number of BFP entries.
  • Corrected: An issue that Vigor router's APM did not support AP1062C.

Known Issue

  • This version (4.4.3.2) introduces support for admin password hashing. If the router is upgraded to this version and later downgraded to a previous firmware version, the admin password will reset to its default value. It will be necessary to log in using the default password and reconfigure it. Other settings will remain unaffected.
  • TR-069 parameters for Application >> Smart Action is not completed.
  • The web portal may cause the router to be too busy to respond quickly.
  • The encryption method for OpenVPN will be returned to the factory default settings if upgrading the firmware version from V3.9.7.x to V4.3.1.
  • To prevent potential errors when upgrading firmware, it is recommended to upgrade firmware sequentially one version at a time. (e.g., if the current firmware is 3.9.1, upgrade to 3.9.2 then 3.9.7.2, and then the latest version).
  • When the firmware is downgrading via "System Maintenance > Firmware Upgrade", one might have a chance to experience a config compatibility error, which causes the config of a certain function to return to the default setting. To avoid this error, “System Maintenance >> Configuration Export >> Restore Firmware with config" is the preferred way for firmware "downgrading". We suggest backup the config file before upgrading any firmware as well.
  • Inter-LAN routing setting exported/backed up from firmware 4.3.2 release might be incorrect, please check inter-LAN routing settings.
