Have you restarted your server since?
Try resetting your router and re-forwarding.
Some people have issues resetting, because sometimes you have to do specific things.
If you've got a LinkSys router, there should be a button on the back that's for reset. Hold it down for 10 seconds, and your router should be reset to "linksys" thus making any portforwarding or anything of the sort removed, which should give you a blank slate to start with and having you with no errors as of yet which could in turn screw up working stuff.
