AsusWrt-Merlin Firmware 380.58.0 for RT-AC66R Description

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:

- NEW: Merged with 380_1354 GPL
- NEW: Added Tweaks and Hacks settings to Tools -> Other Settings. These are UNSUPPORTED tweaks, intended mostly for experimentation, or very specific situations. If unsure how to apply these, manually reboot after changing them.
- NEW: Added setting to configure OpenVPN's auth digest algo.
- NEW: Added setting to configure OpenVPN's logging verbosity. Note that this setting is global to all clients/servers.
- CHANGED: Updated OpenVPN to 2.3.10
- CHANGED: Updated openssl to 1.0.2g
- CHANGED: Updated miniupnpd to 1.9.20160222
- CHANGED: Updated udpxy to 1.0-build 23-10 (backport from GPL 380_2345)
- CHANGED: if you set an OpenVPN client DNS mode to "Exclusive" and you enable policy-based routing, then those policies will also determine which DNS to use (the tunnel's or the ISP's). This is based on DNSFilter's technology. You no longer need to use DNSFilter to control the DNS used by your OpenVPN clients.
- CHANGED: Made OpenVPN traffic bypass CTF, which resolves some throughput issues with it
- CHANGED: Disabled X11 Forwarding support in Dropbear, for security.
- FIXED: PPTP static route handling script was broken
- FIXED: minidlna would check for the wrong database filename at start time
- FIXED: Wrong status shown for VPN Client 3
- FIXED: OpenVPN clients were run on the wrong CPU cores. Now, odd instances correctly run on the second core.
- FIXED: Using DNSFilter with default mode set to "router" would prevent using the router for IPv6 lookups.
- FIXED: Account limit wasn't properly allowing up to 10 clients for SMB/FTP (patch by vit9696)
- FIXED: Having multiple OpenVPN clients configured with multiple "Accept DNS configuration" modes would only apply the last client's setting. Now, we apply the most restrictive setting of all configured clients.
- FIXED: RT-AC68U 2.4 GHz was broken if CTF was disabled (downgraded wifi driver to 6.37.14.105)
- FIXED: Disabling the SIP NAT helper would also drop all port 5060 traffic. Some users need to keep the SIP helper disabled with their SIP client. Reverted that GPL 858 change.

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.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
