it really depends on what you want the world to see.
here's some questions for you
- do i want to provide http to the outside world , if yes, port 80 should be
allowed and maybe 443 for https
- do i need my server to provide DNS services, if yes port 53
- do i need mail to be send to that server, if yes port 25
- do i need ssh access from external, if yes 22
- do i need ftp or other services accessible from external, see respective

the bottom line is, you can follow the european way, i.e only allow what is
neccesarry, or follow the us approach, allow everything and deny certain

so from dmz to external you should allow at least

from external to dmz
only allow httpd

than add whatever protocolls you really need. remember, security is always
the hassle between personal freedom and a better feeling when going to bed
at nite.
