BlueBust

BlueBust is a special setup that gets past BlueCoat (and other deep packet inspection) filters. It is cross platform, versatile, and very secure. Use the base install but set the client to listen to the localhost, as well as the server. Stunnel provides the wrapper, which bypasses the BlueCoat Deep Packet Inspection filters, regular OpenVPN traffic will not be able to breach to the outside of the network, which makes this extra encryption a necessity.

Server

Install stunnel

sudo apt-get install stunnel4

Create self-signed key

openssl req -new -nodes -x509 -days 3650 -out /etc/stunnel/stunnel.pem -keyout /etc/stunnel/stunnel.pem Next configure stunnel to listen and connect on respective ports by editing /etc/stunnel/stunnel.conf

cert = /etc/stunnel/stunnel.pem
 
[openvpn]
accept = 443
connect = 1194

Then edit the ENABLED variable to 1 in /etc/default/stunnel4 sudo vim /etc/default/stunnel4 Then restart stunnel sudo service stunnel4 restart

Client

Install stunnel also on the client Windows Download sudo apt-get install stunnel4 Then use this config

[openvpn]
client = yes
accept = localhost:1194
connect = {ip}:443

Then restart stunnel
