Can OpenVpn Network traffic be finded

Post by chehelstoon » Tue Aug 25, 2020 9:36 am

Hi

I live in Iran and the regime of Iran has filtered a lot of foreign websites
for bypassing the censorship I have configured OpenVpn on a VPS which is abroad (in Germany) , and I transfer all my Internet traffic through that

Now I what to know , Can the regime of Iran eavesdrop Internet traffic and find out than I am using OpenVpn ?
Or , Does OpenVpn Network Traffic have special or unique characteristics , that they can use it to find out that I am using OpenVpn ?

For example , I know that they can find Tor traffic and they have blocked Tor , Do they can find OpenVpn traffic too ?


Thank you

Who ever controls the network controls the universe ..

Yes, they can and probably will detect that you are using a VPN.

They may already have done so but have not blocked you yet ..

Depends on configuration.
and find out than I am using OpenVpn ?
Yes.
I gloomily came to the ironic conclusion that if you take a highly intelligent person and give them the best possible, elite education, then you will most likely wind up with an academic who is completely impervious to reality.

A new law is passing through the Congress that says "Every body who prepare and issue VPN will be send to prison"
Now , can I use a special configuration that they can't find me ?

stunnel.
It will look exactly like HTTPS.

But if they are advanced enough they could still do pattern recognition in the traffic flow and decide to take action.
And you are connected to one destination constantly which is also a hint...

Depends on configuration.
To be clear: Using up to date OpenVPN (Version 2.5), server and client, with default configuration:
  • The data inside the tunnel can not be eaves-dropped / deciphered.
  • However, that you are using a VPN is clear to see.

If your government are threatening you then you would be wise to heed their warning.

No. There is no possible way to hide from your Internet service provider and therefore your government. If you use a VPN then this will be detectable no matter what steps you take.

@TinCanTech
I see no disagreement.
