As a tag on to this, set a solid hardened ( to your level of tin foil) firewall, complete with replacing router with open|DDwrt one and setting up a VPN over ssh from within your own home network, this has several benefits, you know the holes in the firewall, you use the bandwidth you are paying for already, it makes for a relatively cheap private cloud that also allows for smaller and or lighter footprint devices that can stream remotely from your home storage and also know that your nfs / remote cloud is under control of someone you trust (yourself)
