Stealth profile Android

Recommended Posts

Hi all,

 

Torvpn is able to make stealth profiles for android that work in China.

 

Any possibility to have this for Airvpn?

 

See examples below for both TCP and UDP for one of their servers in the Netherlands

 

client
dev tun
proto tcp
nobind
remote-random
remote 89.248.172.172 443
ca ca.crt
auth-user-pass
remote-cert-tls server
cipher AES-256-CBC
resolv-retry 5
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
route-delay 5 30
ping-restart 0
persist-key
persist-tun
comp-lzo
mute-replay-warnings
client
dev tun
proto udp
nobind

Hello!

 

The problem in those configuration files is that the OpenVPN "fingerprint" is always visible in the headers, so the connection can be disrupted. We solved the problem by encrypting the OpenVPN header, tunneling OpenVPN in SSL or SSH (OpenVPN over SSL/SSH, a tunnel inside a tunnel). This solution works in China and Iran, the two countries in which OpenVPN connections are actively disrupted, but as far as we know (we will investigate further anyway) it can't be implemented on Android or iOS because openvpn-connect client does not support connections of OpenVPN over SSH or SSL.

 

Kind regards

Hi,

 

Thanks for your response.

 

I was in China recently and sometimes the AirVPN profiles worked (resolved IP configs)

But sometimes they didn't and the 'stealth' config from Torguard did work.

What do you think of this patch that was made that adds a possibility to scramble vpn traffic?

Hello,

 

it is not simple to implement it in our service, there are serious issues. Anyway our reports from China are very good, there is no need at the moment to add anything else, especially something so problematic like the proposed patch.

 

Kind regards
