AsusWrt-Merlin Firmware 3.0.0.4.378.50 Beta 1 for RT-AC68U 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.

IMPORTANT:

- You must do a factory default reset, and manually configure your setting. Failure to do so can lead to various issues with wifi, OpenVPN, and the new AC68U bootloader.
- Please read this changelog, especially the changes related to jffs, user scripts/config and OpenVPN.

Changes:

- NEW: Merged with Asus 378_3913 GPL code. Most notable changes: Trend Micro DPI engine for RT-AC68U, updated Trend Micro engine for RT-AC87U, Updated Quantenna firmware/driver, and various updates to 3G/4G support and Dual WAN
- NEW: ddns-start user script, executed after the DDNS update was launched (can be used to update additional services)
- NEW: Custom DDNS (handled through ddns-start script)
- NEW: Option to enable support for custom scripts and config files. This option is disabled by default, so if you have a broken script that prevents the router from booting, doing a factory default reset will ensure that the broken script won't be executed, and recover access to the router. This is necessary since the JFFS2 partition is now enabled by default.
- CHANGED: Added logo to DNSFilter on the AiProtection homepage (contributed by Piterel)
- CHANGED: Updated Openssl to 1.0.0p
- CHANGED: Merged Asus's newer NTP update code, with a fix to prevent hourly log spam from the update process when in a DST enabled timezone.
- CHANGED: Updated vsftpd to 3.0.2 (newer version used by Asus on their Qualcomm-based routers)
- CHANGED: the qos-start script will be passed an argument that will contain "init" (when setting up tc) or "rules" (when setting up iptables).
- CHANGED: JFFS2 partition is now enabled by default, to be in sync with Asus, who are starting to make use of this partition.
- CHANGED: The Local IP in an IPv6 firewall rule can now be left empty.
- CHANGED: Download Master will now be downloaded at install time rather than included in the firmware, to increase the amount of space available to JFFS- this matches the AC56/AC68. (N16, N66)
- FIXED: Under certain conditions, the OpenVPN server page would report an initializing state when it was already running.
- FIXED: First OpenVPN client/server instance wasn't properly run on the second CPU core, resulting in lower performance (AC56/AC68/AC87)
- FIXED: Router IP wasn't advertised through DHCP as WINS server if WINS was enabled
- FIXED: OpenVPN would crash if specifying "None" as the cipher (regression in OpenVPN 2.3.6)
- FIXED: The "empty" category was removed by Asus a few months ago, preventing you from removing an assigned priority on the Adaptive QoS page. Re-added it.
- FIXED: Port triggers weren't written to the correct iptables chain (Asus bug)
- FIXED: When moving from stock to this firmware, the OpenVPN Server 1 instance gets automatically enabled because Asus hardcodes "1" into the nvram setting that handles start at wan. Changed to a different nvram to resolve this conflict. This means everyone must re-enable their OpenVPN server instance after upgrading from any version before 376.50.
- FIXED: dnsmasq would run out of available leases if you had a very small DHCP pool combined with many out-of-pool reservations. Now the limit will be either 253 or the pool size, whichever is the largest (Asus issue)
- FIXED: SSHD port forwarding couldn't be enabled/disabled
- FIXED: DHCP log spam when using IPv6 with a Windows 8 client (patch by pinwing)
- FIXED: snmp exposes a lot of sensitive information such as login credentials, therefore all the custom Asus MIBs have been disabled.
- FIXED: Very long SSIDs with special characters/spaces in them would be shown as "undefined" in the banner.
- FIXED: Curl would fail to access SSL sites due to lack of a CA bundle.

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.

  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.
