First I want to start by saying I have a Linksys Cisco e4200 I went to portforward.com and followed their tutorial http://portforward.com/english/routers/port_forwarding/Linksys/E4200/Minecraft_Server.htm I've double checked everything that this tutorial told me, but it doesn't seem to be working.
Check out my tutorial on port forwarding, or even the tool to do it for you. jacklin213 also has a great tutorial, so i recommend trying all three and seeing if it works.
