I am currently unable to forward the local IP for my elastix PBX to the public IP of the cisco router it is connected to. I SSH into the PBX and was able to ping yahoo just to make sure that the box is reaching the internet. I even forwarded other devices (eg phone) to the public IP of the router and could see them from the internet. However when the box IP is forwarded I am unable to see the box, this make me unable to remotely manage the box. can some assit here please.
