ASUS RT-AC87U AsusWrt-Merlin Firmware 384.7 Beta 3

The AsusWrt-Merlin firmware was developed with the primary goal of boosting the original ASUS firmware, fix bugs and also add new improvements. This package includes a customized firmware targeted at ASUS routers that brings various changes without modifying the interface of the original firmware.

Changes:

- NOTE: The RT-AC3200 and RT-AC56U are not supported by this release, Asus hasn't released any updated code for these models.
- NEW: Merged with GPL 384_21152.
- NEW: Merged RT-AC87U binary blobs + SDK from 382_50702.
- NEW: Replaced old ez-ipupdate DDNS client with inadyn. A plugin was developed to fully support Asus's DDNS service. Custom services can now be configured through ddns-start inadyn.conf.add, or inadyn.postconf. See the inadyn documentation as many custom services can be defined for it.
- NEW: Added support for freedns.afraid.org DDNS service to webui.
- NEW: Added option to retrieve WAN IP from either the local interface (like before) or through a remote server (which works through double NAT) for DDNS.
- NEW: Display DFS channel info on Wireless Log page.
- NEW: Added option to disable checks on unsigned DNSSEC replies. Disabling these will speed up lookups, but it will also remove part of the security benefits of DNSSEC, so it should not be used unless you have a very specific reason to do so.
- NEW: Added Quad9 to DNSFilter supported services.
- CHANGED: Updated curl to 7.61.1.
- CHANGED: Updated wget to 1.19.5.
- CHANGED: Updated openssl to 1.0.2p.
- CHANGED: Updated dnsmasq to v2.80test4 (themiron).
- CHANGED: Updated nano to 3.1
- CHANGED: All DDNS services now use HTTPS.
- CHANGED: Replaced Google Domains DDNS script with inadyn's own plugin.
- CHANGED: Moved DNSFilter to the LAN section, to make it clear that it's unrelated to Trend Micro's engine.
- CHANGED: Report hostname and IP on Wireless Log page if the info is missing from dnsmasq but available from networkmap.
- FIXED: Invalid dnsmasq config when setting DNSFilter to Router mode and having IPv6 enabled (themiron).
- FIXED: dnsmasq crashing on RT-AC86U with IPv6 Stateful mode (themiron)
- FIXED: client table would be shown twice on the VPN Status page if the only connections to an OVPN server were invalid clients (like a port scanner)
- FIXED: DDNS forced updates after "x" days wouldn't be fired.
- FIXED: CERT VU#598349 vulnerability (DHCP client could claim the special "wpad" hostname)
- REMOVED: Ez-ipupdate DDNS client (replaced with inadyn). Update your scripts if you were relying on it.
 - REMOVED: Norton Safe DNSFilter services (being discontinued by Norton in November). Configured clients will be automatically migrated to OpenDNS Family - make sure to edit your DNSFIlter settings if you desire to use a different service.

Installation Notes:

- This custom firmware can be applied like any regular update.
- You should not need to reset to factory defaults.
- You can revert back to an original ASUS firmware at any time.
- Do not load a saved copy of your settings. 

About Router Firmware:

Before you consider downloading this firmware, go to the system information page of the router and make sure that the currently installed version isn't either newer or matching this release.

Due to the large variety of router models and different methods for upgrading the device, it is highly recommended that you read and, above all, understand the installation steps before you apply the new firmware, even if you are a power user.

In theory, these steps shouldn't be much of a hassle for anyone, because manufacturers try to make them as easy as possible, even if they don't always succeed. Basically, you must upload the new firmware to the router through its administration page and allow it to upgrade.

If you install a new version, you can expect increased security levels, different vulnerability issues to be resolved, improved overall performance and transfer speeds, enhanced compatibility with other devices, added support for newly developed technologies, as well as several other changes.

If you're looking for certain safety measures, remember that it would be best if you perform the upload using an Ethernet cable rather than a wireless connection, which can be interrupted easily. Also, make sure you don't power off the router or use its buttons during the installation, if you wish avoid any malfunctions.

If this firmware meets your current needs, get the desired version and apply it to your router unit; if not, check with our website as often as possible so that you don't miss the update that will improve your device.
