# Network services, Internet style
#
# Note that it is presently
the policy of IANA to assign a single well-known
# port number for both TCP
and UDP; hence, most entries here have two entries
# even if the protocol
doesn't support UDP operations.
# Updated from RFC 1700, ``Assigned Numbers''
(October 1994). Not all ports
# are included, only the more common
ones.
#
# The latest IANA port assignments can be gotten from
#
http://www.iana.org/assignments/port-numbers
# The
Well Known Ports are those from 0 through 1023.
# The Registered Ports are
those from 1024 through 49151
# The Dynamic and/or Private Ports are those
from 49152 through 65535
#
# Each line describes one service, and is of
the form:

자주 쓰는 프로그램, 서비스의 포트 번호
포트 포워딩을 하려면 인터넷 서비스, 소프트웨어가 쓰는 포트 번호를 알아야 한다. 사람들이 많이 쓰는 네트워크 서비스, 메신저, P2P 프로그램의 포트 번호를 정리한다.

여기에 나오지 않은 프로그램의 포트 번호는 소프트웨어 제조사에 물어보면 알 수 있다. 몇몇 프로그램은 정해진 포트 번호를 쓰지 않고 사용자가 마음대로 정하는 메뉴를 둔다. 그런 프로그램을 쓴다면 포트 번호를 10,000번보다 높은 숫자로 정하는 것이 좋다. 이렇게 하면 다른 프로그램과 포트가 충돌하는 문제가 생기지 않는다.
