Blocking P2P at Layer 7 - Does VPN circumvent?

[RumorConsumer]

I think this is wise for me as I have a lot of guests come and go. So I switched it on on my WLAN, both SSIDs - regular and guest. I don't want any complaints. 

If somebody decides to torrent and they use a VPN, it will likely evade this rule, but then it would also evade anybody in law enforcement who would blame us, right? 

Bonus points - For that matter, does VPN circumvent all Layer 7 rules?

Damn right, sir. The only thing the infrastructure will see is the VPN tunnel. Everything that‘s inside of it is being effectively hidden...which is the definite reason to use it. 😉

For that matter, VPN will also circumvent Layer 7 rules. The only Layer 7 rule coming into play is the one for the „outer“ traffic, aka VPN tunnel.

Ok this is fine. I don't care if people do it as long as its protected. My bandwidth rules will still apply which is really what I care about.

If you had an MX, you could try blocking 'proxies and anonymizers' to help with this but uh... I think you'd have a lot of angry customers. It also wouldn't solve the problem of people using private RA VPN setups.

I want to force people to be safe about it and not expose us to problems. So if I ban it from Layer 7 in those settings and they find a way around my protection and law enforcement at the same time thats on them.

@RumorConsumer  Yes users will be able to use P2P software over VPN, that is why so many VPN app's have shown up in the last 2-3 years as a means of getting around content filtering and application firewalls. 

VPN is part of a teenagers lingo these days. 

[RumorConsumer]

Party on crazy teenagers with their encrypted tunnels. Never change.

Whats next the warn on VPN?

[RumorConsumer]

Haha thats funny. VPNs are corrupting America's youth.

[Nash]

Nahhhhh, trust me, the youth have been perfectly capable of corrupting themselves since we were all youth. It's the joy of growing up.

Yes that was dry sarcasm. I’m one of em. Er, was?
