Question : Problem: When connected to VPN, cannot access secure HTTP sites

I use the VPN to connect to the office a lot, and in order to access an web sites with HTTPS I have to disconnect from the VPN.

Is there a way to tell Internet Explorer to use my ISP Internet Connection instead of using the VPN connection for the Internet? or perhaps a way to change to get HTTPS website to work when connected through the VPN?

What type/manufacturers VPN client are you using?
If the Windows VPN client, you should be able to go to Network Connections, right click on the "Virtual"/VPN adapter and choose properties, next networking, then Internet protocol TCP/IP properties, Advanced, and uncheck "use default gateway on remote network" on the general tab.
Keep in mind this is a security feature protecting the remote network from local connections.
