Preface: Previous post Reviewing Privacy Guides's Criteria for VPNs, and Cryptostorm and AirVPN was deleted due to having multiple criteria suggested instead of one per post for some reason, so breaking it up here. If you disagree with something, please be constructive and specific so a discussion can be had.
This is Post/Suggestion 2: Port Forwarding
I think we ought to include options that support port forwarding be included (for various applications and connectivity uses, including torrenting–note there are non-piracy based legal use cases for this for people circumventing oppressive regimes as well). However, out of the available options on Privacy Guides (Mullvad, IVPN, and ProtonVPN), the former two have no port forward support at all (they dropped it within the past year), and the latter by PG’s own admission has “limited" support.
As a baseline, if we consider what other criteria one might consider make a VPN a supporter of privacy, security, and anonymity, one might start with the basics: having no logs, no analytics, anonymous payments (meaning they accept at least one of either XMR or cash), and anonymous registration/logins (i.e. email is not required and/or generates a random alphanumeric “account”), and is (relatively) well known [such as showing up on Techlore’s list VPN Comparison Tool | Techlore VPN Toolkit ], we have: Mullvad VPN, IVPN, Windscribe, hide\.me, AirVPN, Cryptostorm, AzireVPN, and ShockVPN. Now, if we narrow this to only those that have port forwarding, we have: AirVPN, Cryptostorm, AzireVPN, and ShockVPN [Windscribe is excluded because they expire after 7 days, but will mention anyway]. Finally, if we further constrict the options to the larger of these providers (just to simplify the options and use age/time existing without security issues as a useful benchmark), that leaves AirVPN and Cryptostorm.
So, why not add Cryptostorm and/or AirVPN (or others) since this would allow us once again to have options that allow port forwarding, which is vital for many applications, locations, and services?
Edit/Double Clarification: I’m not saying that those that don’t have to be removed. Not everyone wanting a VPN will need it to have port forwarding, and I get that, but when many applications and services require it, it should be an option. Even the guide right now says: “[not having port forwarding as a] feature could negatively impact certain applications, especially peer-to-peer applications like torrent clients.” So it’s literally acknowledged in the guide as a downside already.
