We are currently using a VPN when accessing the internet. At work we have comcast in which the system works great. When attempting to use the system at home (sbc, tech support was no help after 1.5 hours of trouble shooting) I can run the internet without the VPN successfully but as soon as I log into the VPN to work I receive "the page cannot be displayed". What can I do to get my home internet to work when logged in to the VPN? Any suggestions would be great!!!
