Using VPN trhu enterprise Proxy (VPN Unlimited servers)

FrossiPENA

Hello Guys,

I'm completely new to OpenVPN and i'm trying to make a way thru my company proxy.
I use VPN Unlimited, but the builtin app doesn't connect.
So, I generated the config file from VPN Unlimited and tried to use on OpenVPN.
What I did is:
On the Windows GUI, imported the config file generated from VPN Unlimited Website
Edited the Config File, changed "proto udp" to "proto tcp"
On the Windows GUI, went over Config -> proxy --> Manual, and entered the HTTP proxy settings: 192.168.0.1 : 3128

When I hit connect, i get the msg: "HTTP proxy returned a bad status".

Any idea of how to overcome this issue?

Hey guys, some news:

I know that the proxy filters http keywords. So, i was afraid that I filtered the adress of the VPN server.
I resolved the IP address of the vpnulimited server using traceroute.

Didn't worked.

Is there any way to secure the connection (ex: SSH) without server side access? Or any other way to bypass the company proxy?

You know you are wasting your time ..

FrossiPENA

I really need to bypass. I use a certificate stored on cloud that is inacessible by the proxy.

Then ask your network administrator for access ..
