I am running Norton Security Suite and Windows PPTP VPN. When the VPN tunnel is open all internet activity is extremely slow, speedtest results are 1.5mbps down and .8mbps up. When I turn Norton firewall off the speedtest results are 92mbps down and 25mbps up on my Comcast High-speed Internet. I have tried different computers running XP, Vista, and Windows 7 with different varieties of software loaded – all act the same. Does anyone have any idea as to how to resolve this? I cannot use any other VPN than Windows VPN.
