Download Firmware Asuswrt-Merlin 386.4

Asus uses a Tomato-derived firmware called Asuswrt for its routers, such as the RT-AC68 and RT-AX88. This firmware is, except for a few drivers, open source, with closed binaries included. Asuswrt-Merlin is in turn a modified version of the original firmware from Asus. It includes bug fixes and minor improvements, but still tries to stay close to the original, so that it remains possible to add new features that Asus introduces to the code. The most important improvements from version 386.4 are listed below:

The highlights of this release;

• Merges with GPL 386_45958.
• Adds support for the RT-AX86S (uses the same firmware as the RT-AX86U).
• HND firmware now includes both the kernel module and userspace tool for Wireguard. There is no built-in support for Wireguard at this time, these are only included for end-user or third party usage. Asus is still working on their own implementation, which isn’t available yet.
• OpenVPN server now supports IPv6, both for incoming connections, and for routing access to the LAN clients over IPv6. Note however that redirecting IPv6 Internet traffic through your server is not supported.
• Component updates: curl 7.79.1, vsftpd to 3.0.5, openssl to 1.1.1m, wget to 1.21.1, nettle to 3.7.3, dnsmasq 2.86, openvpn 2.5.5, tor 0.4.5.11, miniupnpd 2.2.3- git 20211017, inadyn 2.9.1 and amtm 3.2.2.
• jitterentropy-rngd was replaced by haveged. Haveged is more resource-intensive, but it works properly under older 2.6.x kernels.
• dnsmasq was reverted back to using nettle for its DNSSEC crypto handling (since openssl support never got mainlined and was increasingly problematic to support)
• miniupnpd now uses the real public IP address instead of any potential (double-)NATed address for the WAN.
• Reworked DHCP hostname support to use Asus’s own implementation.
• A couple of various bug fixes
