dear all,

a few days ago I deployed an ovpn solution in a medium sized company. One of the two ends of the vpn network is passing through a proxy with NTLM authentication. ovpn has problems to recognize the authentication because immediately after sending the message type 1, the proxy sends no response, so I had to modify the source code by replacing the current message with a similar but different one.

in particular this one:

Code: Select all

TlRMTVNTUAABAAAAAgIAAA==
become:

Code: Select all

TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAFASgKAAAADw==
A detail of the work is available at:

I was wondering if you could have a function that supports this type of proxy (such as McAfee Web Gateway).

thank you very much.
