[ale] iptables and ftp...

[pekstrom at rugrat.org (Peter Ekstrom)]

Bob,

I did a search on google for linux and iptables and found the following
URL which looks failry useful:

http://www.telematik.informatik.uni-karlsruhe.de/lehre/seminare/LinuxSem/downloads/netfilter/iptables-HOWTO.html

According to this you should be able to specify a range of ports like
this:

	--source-port n     (just one port)
	--source-port n-    (greater or equal to port)
  --source-port -n    (less or equal to port)
	--source-port n-n   (range of ports)

The same goes for --destination-port

Hope this helps.

Regards,
Peter Ekstrom
