Encryptive software interrupting internet

Hello:

This is a more of a general VPN question.  I work at a convention center and we provide many different exibitors with internet service (for exhibits/displays).  I have been there for a couple of months and I am noticing that sometimes some vendors come in with VPN software installed on their Laptop's (to connect back to their office) and only these specifc laptops cannot access the internet.

I try trouble-shooting the problem and it always seem to be device specific.  Others do not have any problems connecting, our laptop do not have any problems getting on the internet.  I increase their bandwidth and try giving them PUBLIC IP Addresses.  

What I have seen to work is when I have recommended to these vendors to disable or enable the VPN software (just to trouble-shoot the problem) then they can connect.  Hence it is something software specific on their laptops.

Its not for all VPN software; but, for some.  Also I can ping the default gateway, from these laptops; but, I cannot ping outside world.  Again on our laptops, that do not have any VPN software, work fine.  

My question is why does some VPN software programs interfere with an internet connection?  We have a T3 connection from our ISP cable company.  We have a lot of bandwidth.  It does not matter if I give them a

Private Static IP
Public Static IP address
Increase bandwidth

Does anyone know why some VPN connections may cause some internet connection not to function?  Again we have a T3 connection from our Local Cable Company.  I will call the cable comany and ask them; but, does anyone have any ideas?

Thank you,

Do you mean these users can connect to their office with the VPN software, but not connect to the Internet, or they cannot connect to either?

With VPN clients it is very common to set them up not to allow "split tunneling". This forces all traffic to the remote (office) network and blocks all local or Internet access, intentionally, as a security feature to protect the remote network from the local network. For example if split tunneling were allowed, and a user had an un-firewalled local connection at the same time, it might be possible for another local user to gain access to the other users corporate office through the VPN tunnel. Some VPN clients, such as the Windows client, can be configured to allow both, but others such as the Cisco client have to have split tunneling enabled at the corporate end. Having said that, any user disconnecting or disabling the VPN client, should have local Internet access.
