Hi all,  
I’m setting up Ruby in a non-conventional environment where I need to  
specifically open a port on the box to allow for outbound network  
traffic. So I’m trying to figure out which port RubyGems uses when it  
goes out to the various repos to look for packages.

I’m guessing it’s port 80. Is that correct?

Thank you,  
kodama
