Ok when you are hosting off a home computer and it shuts down, your local Ip changes (ie: 192.168.1.101, when you shutdown you could then get 192.168.1.103) then your router gets confused and you would be able to get threw router so you have to check every time you restart your computer to make sure you local Ip is the same as the one your router is looking for to forward.
