Rookie problem! This machine uses Phpnow to set up the forum lets the outside network access
The great God, teach me, I applied for 3322.org dynamic domain name, the route also did port mapping, domain name is tututowm.3322.org, let the external network access this address is my phpnow,, how I let the outside network access to my Phpnow inside of the website! Who can tell me the specific steps are greatly appreciated, I am a rookie self-study, tinker not come out ...

------Solution--------------------
Phpnow you need to modify httpd.conf to point the domain name to the directory where BBS is located

Locate DocumentRoot to change directories to the directory where the BBS is located, or set up a virtual host
