This tutorial shows how to connect a DD-WRT router to LimeVPN servers via the OpenVPN protocol, using a script.

1. Go to Administration → Commands in your router settings.

2. Paste this whole text to the Command box:

#!/bin/sh

USERNAME="username"
# Replace "username" with LimeVPN username provided by LimeVPN  

PASSWORD="password"
# Replace "password" with LimeVPN password provided by LimeVPN

 

# United Kingdom

REMOTE_SERVERS=remote xxx.limevpn.com 1194
# Replace xxx.limevpn.com with desired server address and use 1195 if 1194 doesn’t work

#### DO NOT CHANGE below this line ####
