Hi Guys,

 

So I have tried using both OpenVPN Clients on my Samsung Galaxy S7 and attempting to establish a VPN connection with the generated configuration files however my corporate network is blocked out AirVPN servers... no matter what port I am choosing it fails to connect however my Private Internet Access TCP Port 80 connection works fine.

 

Many thanks for your help.

1. Did you download configuration profiles for TCP port 80?

 

2. Try using a SSL tunnel to connect instead, which should bypass Deep Packet Inspection on your corporate network. Follow these instructions:

 

 

 

Instead of stunnel it is much more convenient to use TLS/SSL Tunnel. To import certificate from the phone it is possible to install Simple HTTP Server. And to import certificates to "Custom Cert Store" just copy the link from the browser which points to the stunnel.crt (I just renamed this file for convenience)

 

The order of actions is the following: 

  1. Install TLS/SSL Tunnel
  2. Install Simple HTTP Server
  3. Copy folder with extracted xxx.ovpn and stunnel.crt to the phone
  4. In Simple HTTP Server
    1. Start it. It will show the link to the local content of the phone
    2. Open in the browser on your phone folder where you copied folder with xxx.ovpn and stunnel.crt 
    3. Long tap on stunnel.crt and copy the link to clipboard
  5. In TLS/SSL Tunnel:
    1. Import stunnel.crt (or xxx.crt if you renamed it) Screenshot
      1. In upper right corner choose "Manage Certificates"
      2. Press the button "IMPORT CERTIFICATE"
      3. Paste the link from clipboard and press "LOAD"
      4. Give any name for certificate you like i.e. stunnel
    2. Create connection Screenshot
      1. Choose "New" in the right upper corner
      2. Give any name you like in the field "Name"
      3. In the field "Connect to" type IP address and port from xxx.ssl from the same folder where you took xxx.ovpn and stunnel.crt. It is after string "connect = xxx.xxx.xxx.xxx:443"
      4. In the field local port type 1413
      5. In the field Root-Certificate choose "Custom Cert Store"
      6. Check all 3 boxes (first is already checked)
      7. Press "SAVE" button
    3. Now use it
      1. Click on connection name
      2. Press the button "START TUNNEL" Screenshot
      3. You will have green light if it tries to establish connection Screenshot
      4. You check log in upper right corner "Show connection Info". If it is successful in the end you will see long list of lines with hexadecimal numbers with Signature Algorithm Screenshot
    4. Delete "Simple HTTP Server"
    5. Go to OpenVPN
      1. import the xxx.ovpn config file
      2. Connect
    6. Use established secure internet connection

To close internet connection you need:

  1. In OpenVPN: Disconnect with button "Disconnect" 
  2. In Tunnel: press the button "STOP ALL TUNNELS"
  1.

Many thanks for the reply! This is very helpful.

 

Yes I did try TCP 80 but this also failed... strange because PIA works on this port.

 

Sorry for being dumb but where do I obtain stunnel.crt?

 

I have the ovpn file: AirVPN_United-Kingdom_TCP-80.ovpn

Can you post your connection logs?

 

Hi Zhang,

 

Thanks for replying, I will do that tomorrow when I'm back in work for you.

 

Any updates on this? Or were you able to get it to work?
