Astrill Setup Manual:Getting started with ASUS Merlin firmware for routers
Install Astrill Router Applet directly onto ASUS Merlin firmware (RMerlin/ASUSWRT-Merlin firmware) routers.
Install ASUSWRT-Merlin Firmware
First check if you have compatible router, and then install ASUS Merlin Firmware onto your router.
ASUSWRT-Merlin firmware supported routers: Asus RT-N16, Asus RT-N66U and Asus RT-AC66U
Developer website: http://www.lostrealm.ca/tower/
Source code: https://github.com/RMerl/asuswrt-merlin
Note: if you have an RT-AC66R or RT-N66R, these routers are exactly the same as the 'U' versions. The only difference is these are sold by large retailers such as Best Buy. You can freely flash Asuswrt-Merlin on these two routers as well.
Enable JFFS on ASUS Router
Enable JFFS before installing the Astrill applet. On router UI we have to enable "jffs partition" and "Format JFFS partition at next boot" under Administration / System tab and reboot router.
NOTE: If you don't see JFFS on settings tab, please verify if you have installed ASUSWRT-Merlin firmware. Make sure you see (Merlin build) next to firmware version.
Install Astrill applet
From Astrill website, goto MEMBERS > VPN Services > Router Set up
Select AsusWRT (Merlin) for firmware, verify your router IP address and then click on Install button.

Ran into Problems?
If you ran into "Segmentation fault" error message at any point, this indicates that you have problem with DNS resolver. This is usually caused by communication between your main router and Asus router.
Fix DNS Resolver:
Under WAN DNS Setting, tick No option for Connect to DNS Server automatically.
Enter DNS of your choice, we used 18.104.22.168 and 22.214.171.124 (Google DNS), and then hit Apply to save changes.
