Making port accessible

Hi all,

I'm trying to install a java program on a server that I want people to be able to play over the internet.  Lets say I want to run my server on computer 12.34.56.789 on port 5678.  From the same computer I can run my client program and get to the server on port 5678.  However, from another computer I can't.  I suspect that the problem is one of security and I don't know how to make port 5678 accessible to outside computers.  Any idea how to make this work?  Thanks for the help.

Is your server running or behind some some sort of firewall?  Or is it behind a router?

It turns out this is exactly what's wrong.  I had to contact the router company for info on how to remove the blocks.  Thanks.
