问题
I want to be able to access my development server from a machine outside of my home.
I have tried to run rvmsudo rails server -p 80, but when I try to access my computer with my IP, I get to the configuration page of my router...
Any ideas?
回答1:
Have you set up port forwarding on your router? What is the make and model of your router?
See there answers for more help:

cant do port forwarding ro my webrick server to access it from the net!

Testing here, to me works like this:
-d = daemon service
-b 0.0.0.0 = make outside access enabled
So, the command is:
$ rails s -d -p 80 -b 0.0.0.0
I hope this can help you.

My guess is that you are already having a service (like apache web server) listening on port 80.
All you have to do, is pick a port that's unoccupied and bind the service to it.
rails s -d -p PORT_NUMBER
Then you must set up port-forwarding for that port.
Last but not least, if you have a dynamic (it changes over time) IP address (most common), you must always know your current IP. (http://whatismyip.com)
Then you can connect to your web app like this
http://CURRENT_IP_ADDRESS:PORT_NUMBER
