    I just came across this in http://openvpn.net/index.php/open-source/documentation/manuals/65-openvpn-20x-manpage.html

    So, are VPN connections generally more secure in TCP mode than in UDP mode?

    I think TCP is safer yes, it's also better when tunneling through TOR because TOR is also a TCP based protocol. Traffic mixes in, where as combining TCP with UDP you do open yourself up to an attack/s vector. I always use TCP if available for this very reason, more VPN providers should offer TCP.

    Well, that's how I read that man excerpt.

    But then I came across this:

    i thought it was go for udp if it's for speed and go for tcp if it's for reliability (because of packet confirmation). :doubt:
    seems it's not that simple then, huh?

    I usually start with UDP, but settle for what works ;)

    Doing three nested VPNs, I tend to end up with UDP>UDP>TCP.

    I don't yet understand why :(
