The description strongSwan VPN Client Apk

Official Android 4+ port of the popular strongSwan VPN solution.

# FEATURES AND LIMITATIONS #

* Uses the VpnService API featured by Android 4+. Devices by some manufacturers seem to lack support for this - strongSwan VPN Client won't work on these devices!
* Uses the IKEv2 key exchange protocol (IKEv1 is not supported)
* Uses IPsec for data traffic (L2TP is not supported)
* Full support for changed connectivity and mobility through MOBIKE (or reauthentication)
* Supports username/password EAP authentication (namely EAP-MSCHAPv2, EAP-MD5 and EAP-GTC) as well as RSA/ECDSA private key/certificate authentication to authenticate users, EAP-TLS with client certificates is also supported
* Combined RSA/ECDSA and EAP authentication is supported by using two authentication rounds as defined in RFC 4739
* VPN server certificates are verified against the CA certificates pre-installed or installed by the user on the system. The CA or server certificates used to authenticate the server can also be imported directly into the app.
* IKEv2 fragmentation is supported if the VPN server supports it (strongSwan does so since 5.2.1)
* Split-tunneling allows sending only certain traffic through the VPN and/or excluding specific traffic from it
* Per-app VPN allows limiting the VPN connection to specific apps, or exclude them from using it
* The IPsec implementation currently supports the AES-CBC, AES-GCM, ChaCha20/Poly1305 and SHA1/SHA2 algorithms
* Passwords are currently stored as cleartext in the database (only if stored with a profile)
* VPN profiles may be imported from files (this is the only reason why the app requests android.permission.READ_EXTERNAL_STORAGE)

# EXAMPLE SERVER CONFIGURATION #

Example server configurations may be found on our wiki: https://wiki.strongswan.org/projects/strongswan/wiki/AndroidVPNClient#Server-Configuration

Please note that the host name (or IP address) configured with a VPN profile in the app *must be* contained in the server certificate as subjectAltName extension.

# FEEDBACK #

Please post bug reports and feature requests on our wiki: https://wiki.strongswan.org/projects/strongswan/issues
If you do so, please include information about your device (manufacturer, model, OS version etc.).

The log file written by the key exchange service can be sent directly from within the application.

Authentication failure despite correct username and password entered carefully multiple times manually and by copying from password manager. Uninstalled. Back to Open VN for me.

Çağdaş Şenel

Sometimes internet connection is lost in the background and you have to reconnect. Any suggestions? Otherwise, it's a solid VPN client.

Trond H

On Android &gt;= 5.0.1 there is a problem when moving between wifi and mobile networks, forcing you to restart the connection manually. I see there is an issue #865 registered in their bug tracker so guess it will be fixed soon.

Lennert Van Alboom

Easy client side config and works great, but occasionally it'll lock up without warning, effectively killing your network connection. Opening the app to turn off the tunnel in those cases results in the phone freezing, requiring a reboot.

Jason Self

This supports IKEv2 key exchange allowing MOBIKE (reacquiring VPN in the background when lost) which simplifies mobile VPN life. Simple enough to use and the log file reader helps tons for troubleshooting initial setup.

Zachary Smith

Update: Fixed this by deleting the cert from the phone and re-adding it. After updating my nexus 6 to android 6.0 the VPN can no longer can load the private key.

Michael Lam

The app works great. Just 2 questions: 1. Is the app 64 bit optimised? 2. AES-GCM is not working when I have a forced proposal in esp. There is no way to enter proposal manually in the app.

Jack Waller

Very stable. Thanks.

Terry Wang

Worked flawlessly with strongswan 5.x on Linux. Android built-in IPsec Xauth PSK had some weird issues on my CM 12.1 1. I lost network connectivity after a while (ping sendmsg no buffer available - I've done all TCP tuning on both Android and Linux VPN Server to no avail) 2. idle connection got closed after a while, strongSwan VPN client keeps it alive, love it! Awesome! Thanks to the developers, you guys rock.

StrongSwan does not automatically boost when my phone restarts.
