Enable OpenVPN Tunnel on OpenWrt

Enable OpenVPN Tunnel on OpenWrt

First we need to install openvpn-openssl

opkg update

opkg install openvpn-openssl

Next we will be using the provided ovpn file instead of OpenWRT config.
It is actually the same thing because OpenWrt converts the config file to a file readable by openvpn but using a vendor provided config is more convenient and less error prone.

In this example we have 3 files

1. The ovpn file provided by your VPN Provider (Netherlands.ovpn)
2. Password File (Password.txt)
3. Certificate File (TrustedRoot.pem)

 Lets take a look at the ovpn file

client
dev tun
proto udp
remote XX.XXX.XX XXXX
cipher AES-128-CBC
resolv-retry infinite
nobind
persist-key
persist-tun
mute-replay-warnings
ca TrustedRoot.pem
verb 3
auth-user-pass Password.txt
reneg-sec 0

Note that ca refers to the certificate file indicated by TrustedRoot.pem
And auth-user-pass refer to the password file.
If your VPN provider uses TLS you need to provide cert and key.

cert my-server.crt
key my-server.key

For this example it is just username and password
The password file looks like this:

username
password

Thats it.

So we upload all 3 files to /etc/openvpn

To start OpenVPN type the below and enter

openvpn --cd /etc/openvpn --daemon --config /etc/openvpn/Netherlands.conf

You should see this in syslog

Sun Sep  7 17:41:35 2014 daemon.notice openvpn[2284]: Initialization Sequence Completed

Next in LuCI

Add a new Interface in this example I call it "hide"
