Hello

We want to install the option of firewall in our LINUX.
I looked for in FAQ of Firewall, but I didn't find the answers for this questionWhich commands Linux Firewall allows for inside machines ?
I know firewall allows all programs as finger, telnet, ftp only if you logged infirewall machine. Is it right ?. I can't do telnet from inside machine to other machine outside ? Is it true ? 
thanks for all help
