Asus gebruikt voor zijn nieuwere routers, zoals de RT-AC66U en RT-AC87U, van Tomato afgeleide firmware met de naam Asuswrt. Deze firmware is, op enkele drivers na, opensource, waarbij de gesloten binaries wel meegeleverd worden. Asuswrt-merlin is op zijn beurt een aangepaste versie van de originele firmware van Asus. Het bevat onder meer bugfixes en kleine verbeteringen, maar probeert toch dicht bij het origineel te blijven, zodat het mogelijk blijft om nieuwe features die Asus introduceert toe te voegen aan de code. Versie 380.59 is uitgekomen en hierin zijn de volgende veranderingen en verbeteringen doorgevoerd:
New:Experimental:
- Merged with 380_2697 GPL. This includes beta MU-MIMO support for the RT-AC87U/AC88U/AC3100/AC5300, and IPTV fixes.
- Option on OpenVPN client/server page to reset them back to the factory default settings.
Changed:
- Added support for codel and fq_codel to ARM models (RT-AC56U and newer).
When enabling Traditional QoS or Bandwidth Limiter, you can now change from the default sfq queue discipline to codel or fq_codel. (based on Kyle Sanderson's Tomato backport)
NOTE: Traditional QoS is currently broken on the newer models (RT-AC88U and up). This is a known issue in recent Asus releases.Fixed:
- WAN -> NAT Passthrough now allows you to determine whether or not to load the NAT helper module for h323, rtsp and sip. Asus's old behaviour is "Enabled + NAT Helper".
- DNSFilter client dropdown now uses Asus's new one integrated with networkmap.
- minidlna now supports refreshing an existing database, so the Tweak setting was updated accordingly
- Enable SPNEGO support in Samba
- Integrated Asus's networkmap into the DHCP reservations page
- Updated Tor to 0.2.7.6
- SSH WAN access will also work over IPv6
- Updated miniupnpd to 2.0
- Fields on the DHCP static lease page are now sortable (original patch by Allan Jensen)
- Daily/Monthly traffic monitoring shows invalid values on the RT-AC88U/3100/5300, even with CTF disabled. Implemented a temporary workaround.
- WPS wasn't working on the RT-AC3200
- Backported security fixes from OpenWRT to Samba 3.6.25, addressing the following: CVE-2015-5252, CVE-2015-5370, CVE-2015-5296, CVE-2015-5299, CVE-2015-7560, CVE-2016-2110, CVE-2016-2111, CVE-2016-2112, CVE-2016-2115, CVE-2016-2118.
- OpenVPN clients set to policy-based routing and Exclusive DNS mode were still adding the tunnel nameservers to dnsmasq, causing both routed and non-routed clients to use them.
