AsusWrt-Merlin Firmware 3.0.0.4.378.53.0 for RT-N66U (VER.B1) 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 Asus GPL 378_4980 (with pieces from 378_4850 for AC56/AC68 and 378_5183 beta for AC87)
- NEW: OpenVPN policy routing. You can select client IPs or destination IPs which you want to route through your VPN tunnel. You can enter a single IP (192.168.0.1) or a whole subnet in CIDR format (for example 74.125.226.112/30). You can optionally block WAN access to these as well when the tunnel goes down.
- NEW: Ad blocker based on Trend Micro's Web Reputation System (WRS). This is an EXPERIMENTAL feature implemented by Asus but that isn't enabled in the stock firmware.
- CHANGED: Updated Tor to 0.2.5.12
- CHANGED: Those providing a signed SSL certificate for HTTPD can now provide chain certificate. The three PEMs must be in that order: client, intermediate, CA. (Patch by sasoiliev)
- CHANGED: The setting to enable the neighbour solicitation filter rule for Comcast's request flooding was changed to "ipv6_ns_drop", and now defaults to "0" as this hack causes issues with other ISPs.
- CHANGED: Backported dnsmasq patch that reverts a fix for Windows 8 clients as it could cause issues with other clients.
- FIXED: DNSFilter would fail if you had it set to "Router", and didn't have a DNS IP entered on the WAN page.
- FIXED: MSS clamping wasn't applied to traffic in both direction, moved it to the mangle table.
- FIXED: OpenVPN client firewall "external" mode does not exist - removed from the webui.
- FIXED: PPTP account list could become corrupted after removing an entry on the PPTP server 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.
