L2TP Part 1 

10 years later and you're carrying me through my course better than my university prof.

Thank you for this video! It is really helpful to me preparing a presentation on the subject

Excellent video. Very informative

Superb....This Video is very informative....:) Thanks!!!

L2TP can be authentificated by using a pre-shared key or ceritifcates which are unhackable, but sadly most VPN companies only provide preshared "secret" keys, which are weak and easily hackable. Why is that? Otherwise very good vid, it's what I've been looking for.

Awsome!
