Download Firmware Synology Router Management 1.2.4 build 8081

Synology has released a new version of Router Management after a long time. SRM is the firmware that runs on Synology’s routers and is in a way similar to Disk Station Manager, the firmware for the same company’s NAS devices. These devices achieve excellent performance, have extensive options and are easy to operate via a clear web interface. In version 1.2.4 the following changes and improvements have been made:

What’s New

• Added support for adding Wi-Fi points to a mesh Wi-Fi system via Ethernet cables during the first-time deployment.
• Allowed a mesh Wi-Fi system to have Wi-Fi points running different SRM’s Update versions (with the same four-digit build number) so as to enhance update experience.
• Added support to configure multicast translation and IGMP snooping in a mesh Wi-Fi system.
• Added support for communication between client devices within the guest network.
• Added support for broadcast storm prevention through MAC filtering, which prevents wireless devices from sending a large number of broadcast packets in a short time and affecting the normal usage of other devices.
• Added support to apply the Default Policy of traffic control to each device connected to the guest/local area network.
• Added support for delivery of traffic reports on the last day of every month.
• Improved the startup speed of Synology Router after an SRM update.
• Enhanced the performance of iPhone USB tethering.
• Unified the behaviors of soft reset on RT1900ac, RT2600ac, and MR2200ac: the username of administrator’s account can be customized during the reset.
• Added support for LCP identification of PPPD settings during a PPPoE connection (required by some ISPs).
• Added support for the IGMP querier timer for IPTV to enhance compatibility.
• Added support for connection tests of DNS over HTTPS (DoH).
• Adjusted the behaviors of data storing: system data will now be respectively stored in each external storage device connected to Synology Router.
• Updated the valid period of default certificate to 398 days in response to the policy change of Apple.
• Enhanced the compatibility of WPA2-EAP/WPA3-EAP with RADIUS servers in a mesh Wi-Fi system.

Fixed Issues

• Fixed the issue where the performance of Synology Router might be reduced when a macOS device connects to it.
• Fixed the issue where iPhone 11 running iOS 13.2.3 might fail to connect to the WPA3-Enterprise wireless network.
• Fixed the issue where SRM might fail to send logs of Wi-Fi points to other log servers.
• Fixed the issue where the wireless network might not work properly after an update of SRM on which configurations have been restored.
• Fixed the issue where packages might not be downloaded properly from Package Center on RT2600ac.
• Fixed the issue where interface failover cannot function properly when either of the WAN interfaces is disconnected.
• Fixed the issue where devices on the guest network might fail to access the Internet when a policy routing rule that directs network traffic through the secondary WAN interface is in place.
• Fixed the issue where users might not be able to select WAN interfaces upon configuring static routing if the IPTV uses 10 as its VLAN ID.
• Fixed the issue where SRM might fail to access the Internet via PPPoE when IPTV is enabled.
• Fixed the issue where IP addresses might not be obtained from ISPs (Internet Service Providers) after Synology Router restarts.
• Fixed the issue where RT2600ac might fail to access certain HTTP IP addresses when it is in the wireless AP mode.
• Fixed the issue where the links of traffic reports in notification emails might be invalid when the task names of reports contain special characters.
• Fixed the issue where the device list on the Traffic Control page might incorrectly display the IP addresses of banned and disconnected devices.
• Fixed the issue where the status of a user account might be shown as “disabled” immediately after it is scheduled to be disabled on a later date.
• Fixed the issue where Synology Router in the wireless AP mode might fail to send packets to specified gateways when there are multiple routers and gateways within the local network.
• Fixed the issue where port forwarding might not work properly with PPPoE connection after Synology Router restarts.
• Fixed the issue where SRM might fail to send notification emails through mail servers with SSL/TLS settings.
• Fixed the issue where SNMP messages might not contain correct SRM information.
• Fixed the issue where SRM might fail to renew the Let’s Encrypt certificate.
• Adjusted the memory parameters for MR2200ac to prevent unexpected restart.

Security Updates

• Fixed a security vulnerability regarding BSD (CVE-2019-20367).
• Fixed a security vulnerability regarding hostapd (CVE-2019-16275).
• Fixed multiple security vulnerabilities regarding Dnsmasq (CVE-2019-15107 and CVE-2019-14834).
• Fixed a security vulnerability regarding Linux kernels (CVE-2017-13168).
• Fixed a security vulnerability regarding CallStranger (Synology-SA-20:13).
• Fixed multiple security vulnerabilities (Synology-SA-20:14).

Known Issues & Limitations

• Due to security considerations, if configurations backed up from a mesh Wi-Fi system running SRM 1.2.3 or earlier are restored on the primary Wi-Fi point running SRM 1.2.4 or later, all Wi-Fi points (except the primary one ) need to be reset and added to the mesh Wi-Fi system again.
• Re-login to Synology mobile applications (DS cloud, DS file, DS get, DS router, and Synology VPN Plus) is required after SRM is updated to 1.2.4.
