I use VPN to connect to my company's wiki/email/etc. when I'm not in the office. Does VPN encrypt all the traffic between my laptop and the Internet (that is, even non-company hosts such as, etc.) or does it only encrypt traffic between my laptop and the company wiki/email/etc. hosts?

If I'm on a cafe's free wifi, will connecting to the corporate VPN encrypt all of my traffic or just my traffic to the corporate hosts?

It is completely arbitrary. The VPN can be setup either way. – Zoredache Apr 3 '12 at 17:38
This site is professional sysadmins. If you are not the administrator of a given system (ie the VPN server), then you are probably asking in the wrong place. – Zoredache Apr 3 '12 at 17:38
The answer to all of your questions is "maybe". – womble Apr 3 '12 at 20:30

well this depends. You can have a VPN from your laptop to your company to access the internal network of the company. In this case only the part between your laptop and your company's VPN end-point will be encrypted.

You can also push all traffic trough a VPN. Mostly this is not the case but it is possible. This would re-route all traffic trough your VPN, making all of your traffic encrypted untill it reaches your companies VPN end-point. From there on it will be unencrypted.

But it is most likely that only the traffic between you and your company is encrypted.

Assuming the VPN is set up to encrypt traffic at all -- Yeah, most are, but I've seen some that aren't. Those make me cry. – voretaq7 Apr 3 '12 at 17:58
terrible tought that that exists and even is possible... – Goez Apr 3 '12 at 18:06
Why? Not all VPNs cross the public internet. Sometimes you only want a Virtual network, and don't need the privacy/security. – Zoredache Apr 3 '12 at 18:09
mostly if you do not cross the public internet, you are still on a private network... – Goez Apr 4 '12 at 6:29
