I currently have my internal firewall running and I have my
ipfw.config set up and currently blocking multiple known spamming
ip address like this:
add deny log tcp from 220.127.116.11/8 to any dst-port 25 in
In reading the server docs and the man pages it is not clear to me
how to block a range of ip's such as 18.104.22.168 - 22.214.171.124
You just provided an example of how to block a range above.
add deny log tcp from 126.96.36.199 - 188.8.131.52 to any dst-port 25 in
add deny log tcp from 184.108.40.206-220.127.116.11 to any dst-port 25 in
Does not seem to work.
Additionally how does one block a range and then allow an ip within
the blocked range? If possible?
ipfw uses "first match wins". ALLOW before your DENY.
Ah OK sorry I missed that.
Pointing me to the correct documentation or a link to an article
would be great but I can't seem to find on on this subject.
Google is your friend. Seriously, didn't you try to Google for
"ipfw"??? Worked for me. ipfw is from of FreeBSD.
Yes I did Google, I guess I posed my question wrong. Thanks!
