Title: VPN services and online-privacy
Post by: DireWolfM14 on April 11, 2019, 02:22:15 PM
In a discussion about a "white list" Electrum server (https://bitcointalk.org/index.php?topic=5130661.msg50557530#msg50557530) that Bitcointalk member mocacinno (https://bitcointalk.org/index.php?action=profile;u=405464) was generous enough to make available to members of the forum, I asked a simple question that brought up more questions.  Rather than derail that thread I'll ask my further questions here.

The question was in regard to using my dedicated IP feature made available by my VPN service provider to connect to mocacinno's server:

I have a question; will it work if send you my dedicated IP that's provided by my VPN service provider?

If you connect to the electrum server via your VPN, yes.

This means.. if you route all of your traffic through your VPN, yes it works.


A little bit off-topic.. but.. Do you have a good reason to use a VPN? Like circumventing geo-blocking / ISP blocking or connecting from an insecure Wifi ?
Because privacy-wise it is horrible to route all traffic through a VPN.

@bob123, could you please elaborate?  Why is a horrible idea privacy-wise, to rout all my traffic through my VPN?  I don't need it for geo-routing, and my wired and wifi connections are secure.

Sure.

You are basically moving the trust from your ISP provider to the VPN provider.
I don't know in which country you live.. but i would rather trust my ISP than a random VPN provider.

The VPN provider can (theortically just as the ISP provider without a VPN) read and modify any non-encrypted (http) traffic.
Even if you visit sites via https, some content might still be delivered without TLS. This includes pictures / graphics for example (which can theoretically be modified to deliver malware).
The question is.. who do you trust more. Your ISP or your VPN provider ?

Additionally, if you install a software directly from the VPN provider, the possibility exists that it installs their certificate as a trusted system certificate.
This would give the VPN provider the option to 'break' the encryption of your TLS secured traffic, leaving them to be able to read and modify ALL of your traffic.

The question is.. WHY do you want to use a VPN?
Most probably there is a better way of accomplishing your goal. If you want to go more into detail here, i will gladly be assisting you here with theoretical concepts on how to achieve that goal.
