I have Comcast as IP and it sits behind a Linksys router. Is there a way I can setup a VPN from my home that I can surf through when using wireless on the road?
Yes, But this would be slow and a real pain. I would recommend OpenVPN on the road, alot easier to setup.
Why are you wanting the VPN routed through your house? Is there a specific reason for wanting it done this way?
Just thought it would be easier. Trying the Tor Project , and also Your Freedom.net right now- but not both at same time.
