Question

[Help Needed] Setting up OpenVPN on DD-WRT Router

Posted December 12, 2016 19.1k views
UbuntuVPN

Dears,
I’ve used this script:
https://github.com/Nyr/openvpn-install

To install an OpenVPN server on my DigitalOcean VPS/Droplet

However I had some rough time getting this to work on my DD-WRT Router:
DD-WRT v3.0-r28788 std (01/13/16)
Router: Linksys WRT1200AC

I’m getting error:
TLS Handshake Failed

I just can’t figure out the correct settings and I would really appreciate it if you give me some help or tell me at least where to search

P.S.: My OpenVPN file works perfectly on Tunnelblick on Mac so I’m sure that there’s nothing wrong with my server installation

My OpenVPN file:

client
dev tun
proto udp
sndbuf 0
rcvbuf 0
remote 46.101.222.212 443
resolv-retry infinite
nobind
persist-key
persist-tun
remote-cert-tls server
cipher AES-128-CBC
comp-lzo
setenv opt block-outside-dns
key-direction 1

You’re likely going to need to follow a guide focused on dd-wrt. As an embedded distribution it can not be assumed that all utilities and prerequisites that would be available on a full server distro would be there. I would start here with the dd-wrt documentation regarding OpenVPN.

Hi @ryanpq
Thanks a lot for your reply
I got it to work finally

I removed all of the extra config and left only:

persist-key
persist-tun

and removed also the checkmark on nsCertType
and finally it connected successfully

For anyone stuck with this kindly check the answer here as well:
