Shorewall suggestion - "services"
...han ports.
In other words, I''d like for there to be a definition-file someplace that says
that "the (say) FTP service requires ports X-Y to be open for TCP and UDP,
and ports X2-Y2 also to be open."
Then I could specify a rule such as:
(from) LOCAL (to) INTERNET (service) FTP_SERVICE (is) ALLOWED
One of the most difficult .. for me, anyway .. aspects of setting up a
firewall correctly is knowing which ports need to be open or closed in order
for a particular service to be correctly activated or blocked. Sure, I could
look up the information on somebody''s web-site...
