Configure static IP with port number which will point to multiple projects on different ports

view story

http://serverfault.com – I am developing a project in LAM* and using the Symfony framework. I have one static IP like which points on my Linux server machine. This static IP already has port number of 8000. This Linux server machine has multiple project hosted on it and we access each project in LAN with different port number like abc:81, pqr:82, xyz:83. Is is possible to access each project on same Linux machine by this static IP? If yes then please let me know how to configure and call each project using this IP address. (HowTos)
