I have a virtual machine installed using VirtualBox. Windows 7 is the host and Ubuntu is the guest. They use a shared Dropbox folder as the DocumentRoot to allow backup and ease of development on multiple devices.
Inside my local network this setup is fine however I would like to be able to develop when I'm outside of my local network but I don't want other people to have access to any of the multiple sites on the web server.
I have a Netgear DG834G with version 5 firmware and I'm comfortable setting up port forwarding and limiting by IP.
Would you recommend looking into setting up a VPN or continue limiting access by IP that I can then change whenever I'm somewhere new (in-laws, parents etc. that don't have a static IP)?
Thanks, James
