We were moving between countries and could not bring it all. Transporting it would be the big hassle, and we dont need the like maybe some 100€ at most we could get for the stuff, so we put it up for free. Lots of people were bringing candy, store bought and even homemade, for the stuff they were getting. Very nice actually.

It does spell trouble, but you might be able to ask your ISP to give you a public IP in that case.

Do you dd the device directly, and while it is running for this?
