I am using the Norton VPN; works correctly with hundreds of websites. So far, the only websites I have found to be incompatible with this VPN are eHam.com and QTH.com. QTH.com displays a message that it is not compatible with VPNs; eHam merely displays the Apache server page and states that the website is down or undergoing maintenance. Could be a setting in the VPN software, but since I have had no other problems, I haven't yet dug into the issue. When I turn the VPN off, eHam works as it should.
