I use Dropbox to backup files on my 12.04 laptop. Currently, whenever Dropbox has an internet connection it syncs. This is an issue when I am tethering with my mobile because of the cost of mobile data.

The Dropbox application doesn't let me choose which wifi networks to use but I can use a proxy server. So I was thinking I could setup a local proxy server with wifi rules.

Does anyone know of a proxy server which has network rules based on wifi? Or does anyone have a better option for limiting Dropbox to particular wifi networks? Apart from simply closing Dropbox ;)
