AsusWrt-Merlin Firmware 3.0.0.4.376.49.0 for RT-AC87U 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.

Fixes:

- NEW: Merged with Asus GPL 376_3677. This new code includes a lot of changes related to USB modem support.
- NEW: IPv6 handling based on dnsmasq + odhcp6c. This new code which has been developed by Asus these past few months but kept disabled so far has been enabled. Initial tests show much better reliability with different ISPs.
- NEW: Added IPv6 support to DNSFilter (currently only Yandex has IPv6 servers). Note that unlike IPv4 filtering, we cannot automatically NAT queries to the desire server, so the current implementation works like Asus's YandexDNS service, where IPv6 servers are simply returned to DHCPv6/RA client queries, and ip6tables ensures that you cannot override them, by rejecting connection to other DNS servers.
- CHANGED: Merged newer DPI engine from 378_3123 beta (AC87)
- CHANGED: Removed SSLv2 and v3 support from OpenSSL (we had already stopped using these in 376.48, so this removes unused code)
- CHANGED: The VPN webui is now a bit closer to Asus's code. This will mostly make it easier to keep in sync with future changes to that UI by Asus (they rearranged the layout a bit in 376_36xx).
- CHANGED: Updated OpenVPN to 2.3.6
- CHANGED: Reverted to Asus's max-lease number calculation for dnsmasq
- CHANGED: Hide wireless key on settings page unless field has focus (patch by John9527)
- CHANGED: Ported USB 3.0 (XHCI) kernel driver from Netgear GPL (which seems to have in turn backported it from upstream kernel 3.x)
- CHANGED: Updated Quantenna to v36.7.3.23 (AC87)
- FIXED: vsftpd wasn't properly compiled with SSL support.
- FIXED: MAC filtering couldn't be disabled on Guest networks (Asus bug) (Patch by John9527)
- FIXED: Various fixes and tweaks to the new IPv6 code from Pinwing and saintdev
- FIXED: Editing a client on the networkmap would cause any matching DHCP reservation entry to lost its hostname
- REMOVED: The web redirection control setting was removed, as it is being replaced by the (simpler) redirection setting Asus added to the System page.

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.
