Frequently Asked Questions

My provider is not listed

You should contact with your provider to double check if there is interest in being added to Passepartout. Beware that some may be concerned instead. Ultimately, you can submit your provider request for a viability review to providers@passepartoutvpn.app.

Why is compression not supported?

Some users may have noticed that Passepartout is not compatible with any compression algorithm supported by OpenVPN. This is intentional and comes from a logical reasoning. Besides being a relevant overhead against marginal gains -most protocols in the application layer (e.g. HTTP) already use compression nowadays-, compression is vulnerable to an attack that may be able to reveal the secret session keys.

The attack is called VORACLE and is extensively explained by the very authors of OpenVPN. Most major providers have taken action and fixed the issue, but many are still refraining to disable compression for no acceptable reason. In case this happens, you are warmly encouraged to report the issue immediately and possibly link to either the official resource you find above, as it comes directly from the software makers, or this page.

BEWARE: it’s not about making the app work, this is about your safety. Do prompt your provider to disable compression ASAP. Most of the time it’s as easy as tweaking a single configuration line on their backends.

Keeping it broken is absolutely irresponsible.

I’m on Wi-Fi but my device shows I’m connected via LTE

The Wi-Fi/LTE icon (replace LTE with any cellular signal) while on VPN has been broken since iOS 10 or the like. It’s something that Apple is unable to fix or doesn’t bother fixing.

You should do a simple test. Verify your data consumption with your LTE provider website, normally phone providers have that. Now, when on VPN and the LTE icon appears in spite of Wi-Fi, download a relevant chunk of data. You may then learn that the plan is unaffected, implying that you’re actually connected via Wi-Fi.

I haven’t found a workaround for this and it’s been there for almost two years. Yeah, it’s a shame.

The configuration file contains an unsupported option (external file)

Due to easier interoperability, the app does not support external files in the .ovpn main configuration. That’s because more often than not, it may not make sense referring to relative paths in a mobile device environment. Think of the Mail app for example. The fix is straightforward though, say you have an external ca file:

ca my-ca.crt

Just replace it with:

<ca>
...
content of my-ca.crt
...
</ca>

The same applies to other settings like cert, key, tls-auth and tls-crypt.

I’d like to see my IP address in the app

The reason why Passepartout does not present any personal information in app is privacy. Obtaining one’s IP address, regardless of being connected to a VPN or not, involves querying -and trusting- a third party service. Knowing such info is also of little use, given that most of the time you don’t want to share your VPN IP address and therefore link your identity to it. However, this feature might be introduced later as a diagnostic tool.
