OpenVPN Client - DNS change; role of 4 FreeVPN.me profiles; How to remove DNS le

[D.Fdo]

I have configured OpenVPN client added and FreeVPN,me bundle. Tested all seems works fine. However I have few quires

How do I know VPN works fine and connection is secured other than OpenVPN green colour icon?

There are 4 profiles – TCP443, TCP80, UDP4000, UDP53; what is the different between them?; why we need 4 profiles?

My home router is configured to use OpenDNS to protect kids from accessing certain contents this includes torrent sites however when I am using VPN I need to access them; therefore how to configure client env to use different DNS or configure to use default DNS of the FreeVPN.me ?

If question two doesn’t answer this; how do I make sure bit torrent will use VPN connection?

FreeVPN,me; does it full tunnel or partial tunnel; if partial tunnel what does it mean to non tech person.

Considering above setup at my house; is there any room for DNS leak? If yes how to fix it.

Note: Lot of words and stuff I grab from reading loads of forums; therefore my apology if I misunderstood them.
