You need at least tftp and bootp (assuming a pxeboot). After that it
depends on the method that you're using to get the image.

It's probably best if you assigned a fixed IP to the machine you're
kickstarting and just opening the firewall completely for that IP ONLY.
Setting up a firewall to permit NFS or FTP can be a pain unless you fix
the ports that the various NFS entities listen on and know how to do
the reverse FTP requests (or use PASV).
