Overview of Vigor 1000B Firmware Updates
The DrayTek Vigor 1000B is a high-performance Multi-WAN Load Balancing Router designed for demanding network environments. Keeping the firmware updated is essential for maintaining security, stability, and access to the latest features. This document outlines the enhancements and corrections introduced in firmware version 4.3.2.
Key New Features
The latest firmware update introduces several significant enhancements to improve usability and network management:
- Multilingual Login Page: Enhanced support for international users.
- Smart Action via Telnet: Improved automation capabilities for network administrators.
- 2FA Authentication: Added support for two-factor authentication for VPN connections to bolster security.
- Switch Management (SWM): Expanded management capabilities for VigorSwitch models including FX2120, PQ2200xb, Q2200x, P1282, and G1282.
Performance Improvements
This release focuses on optimizing existing protocols and modules:
- WireGuard VPN: Improved stability and added support for binding to specific WAN interfaces.
- APPE Module: Upgraded to version 15.27, adding support for Yahoo-related functions and Zalo application enforcement.
- Network Optimization: Automatic MSS adjustment based on MTU settings (MSS = MTU-140) and extended certificate validity for OpenVPN from 1 year to 10 years.
- Mail Service: Increased character limits for username and password fields to 128 characters.
System Maintenance and Known Issues
To ensure a smooth operation, users should be aware of specific maintenance procedures. When performing a firmware downgrade, it is highly recommended to use the System Maintenance > Configuration Export > Restore Firmware with config path to prevent configuration compatibility errors. Always perform a full configuration backup before initiating any firmware upgrade or downgrade process. Users should also be aware that strict firewall rules may inadvertently block remote management, NAT loopback traffic, or VPN access; therefore, reviewing firewall settings is advised before and after major updates. The web portal interface may occasionally experience high CPU usage, which can impact responsiveness during heavy traffic loads.

This is a known issue where the portal may cause the router to be too busy; monitor CPU usage.
