Network address translator

[Jona Villanueva]

hi guys,

my question is this:

i have one valid ip address, but i have several pc's that i want to 
have network access. i am planning to setup a network address translator
so that they all have network access(ftp telnet etc). how do i set up that
kind of service? what are the hardwares needed? i am using redhat-5.2.
