I'm not real technical but I subscribe to a VPN service for when I travel. Gives me a feeling of security and enables me to download US TV from Europe. Once I log into IBAHN, I then log into my VPN. I found that if I logged out of IBAHN prior to logging out of my VPN, I couldn't log back into IBAHN without calling support. As long as I log out of my VPN prior to logging out of IBAHN, I'm fine. Not sure how corporate VPNs work. I assume they automatically log into the VPN when you go online but I don't know.
