Do you have a public IP address?
Discussion
The sassy answer is yes since you kinda need one to connect to anything else on the internet, as it is currently set up.
I do not have a static IP address. I never understood why this is such a big deal, though. (This is my ignorance showing.)
Static would be better, but dynamic would do. I'm asking about it being public because if you are behind NAT it will not be possible to access the relay from the outside.
