VPN Question for Network Guru's

post #1 of 6
Thread Starter 
All,
My Father is going to China for a few weeks and wants to check his stocks/financial information. He asked me if his VPN connection to work (back in the USA) would secure his internet traffic...I wasn't sure (not a network guru *sadface*).

My question is, if he opens his VPN connection to work does all internet traffic go through it or does just corporate stuff go through (email, network file shares, etc).

THANKS!

That will depend on the configuration of the VPN... this is something he needs to ask his company's IT department.

If he connects to his VPN using only a specific application that only does specific things, then not all of his internet traffic will go to his work. However if he connects to his company VPN with his system (more like a tunnel to proxy connection) then all his internet traffic will get routed to his company.

Like the above poster said, ask the IT department about that. There are many ways a connection to a VPN can be configured.

If only certain apps are configured to connect to the VPN then there will be no secure connection for all your other internet applications.

That is not always true. If split tunneling is enabled on the Firewall / VPN Consentrator traffic can go either over the tunnel or over the web. It all depends on the destination IP address, and application settings.

For example: If someone from our work hooks up to a public internet connection, the proxy settings are bypassed automatically so they don't have to go in and change them.

As stated above, he needs to ask his IT department to know for sure.


Kaiga,
I am curious what applications you guys use that can be configured specifically to use a vpn tunnel.

Kaiga,

I don't manage them personally but the one I manage is a set of Cisco ASA firewalls. These aren't tunnel connections though, just vpn.

The senior engineers however manage a a set of Barracuda hardware firewalls and then some software that runs on a blade server (not sure what it is called) for VPN Tunnels connections

He needs to contact his IT department and find out if his VPN tunnel's back to the company's servers. Some VPN software allows you to specifically choose what application has information sent back to the company, such as Microsoft Outlook connecting directly to the company exchange server.
