DD-WRT (OpenVPN at Startup)

Note: OpenVPN only works on Big, Mega and some Std versions of the DD-WRT router firmware. Mini or Micro versions do not work with OpenVPN!

Step 1: Log in to your DD-WRT Web Control Panel

Open your DD-WRT Web Control panel by visiting the IP address of your router (default IP is usually 192.168.1.1) in your browser. Click "Administration" tab.

Enter your username and password (Default usernames and passwords are usually admin/admin, root/admin or root/root)

Now click "Commands" sub-tab.

Step 2: Enter commands

Paste the code below in the Command text input, replace the username and password variables, press 'Save Startup' and then reboot your router.

#!/bin/sh

USERNAME="My_VPNht_Username" # Your VPN.ht VPN passowrd
PASSWORD="My_VPNht_Password" # Your VPN.ht VPN passowrd # udp

# Add - delete - edit servers between ##BEGIN## and ##END##
REMOTE_SERVERS="
##BEGIN##
remote hub.vpn.ht 1194
remote hub.vpn.ht 1195
remote hub.vpn.ht 1196
remote hub.vpn.ht 1197

remote hub.vpn.ht 1199
remote hub.vpn.ht 1200
