This looks like a very cool feature addition to RELENG_7! Are there
any performance penalties that you know of with this built in ?

ipfw "bug" - recv any = not recv any
I hesitate to call this a "bug" as I don't know all the history behind
the ipfw2 decisions, so let me toss this out there and see I'm just
missing something.
Overview
========
The negated operator, "not recv any" was taken to mean "any packet never
received by an interface" believed to be equivalent to "any packet that
originated on the current

ipfw deny or reject - not just a matter of taste?
Hi,
I think this is worth a note.
It was generally said the decision between deny and reject (aka
unreach) could be taken lightly - and most people seem to prefer
"deny", which complicates things for an attacker, because packets
just vanish without any report and tasks timeout.
But from my viewpoint, this argument falls into the category
"security by obscurity", and I found

IPFW: Blocking me out. How to debug?
Dear W.D.
Do you understand that by adding the rules into kernel space numbered from zero to sixty five thousand five hundred thirty four
you may alter the behavior of the rule number sixty five thousand five hundred thirty five
can you please define and list the goals you are trying to achieve by altering default rule in the terms you can both explain and understand.

ipfw table add problem
Hi,
I'm using kernel FreeBSD 10.0-BETA3 #2 r257635 kernel.
I am trying to add port number to ipfw tables. But there is something
strange :
Problem is easily repeatable.
#ipfw table 1 flush
#ipfw table 1 add 4899
#ipfw table 1 list
::/0 0
#ipfw table 1 flush
#ipfw table 1 add 10.2.3.01 ( not 10.0.0.1, the last 1 has 0 as
prefix )
#ipfw table 1 list
::/0 0
#ipfw table 1 delete ::/0

how to get IPFW rules for SMTP server behind NAT server "right"?
hi all,
i've been struggling with setting appropriate rules for an SMTP-server
behind by NAT'd firewall.
it's not that there is too little info on the web -- or here, for that
matter -- there's scads of it for seemingly endless configs/req'ts --
none that seem to be exactly my own.
bottom line: i'm a bit confused, and looking for some experienced
advice.

IPFW Problems
Hi,
I have a system with a 4.11 Kernel. Unless I'm doing something very
wrong, there seems to be something odd with ipfw.
Take the following rules:
ipfw add 00280 allow tcp from any to any 22 out via bge0 setup keep-
state
ipfw add 00299 deny log all from any to any out via bge0
ipfw add 0430 allow log tcp from any to me 22 in via bge0 setup limit
src-addr 2
ipfw add 00499 deny log

ipfw and carp
Hi all:
Did any one use ipfw with CARP before? is there anything specific about ipfw configurations working with CARP? I have two servers and they configured with CARP. they are working fine except i can't turn on ipfw.
I have the exact same configuration except ip addresses; those same rule sets of ipfw work on one server but not on another.
Thanks all

Need help on ipfw IDS support.
Hi,
Is it possible to integrate SNORT with IPFW. I have an entire network behind
an IPFW BRIDGE. Just need IDS capability enabled for the network. Just an
hint is enough. Any other way I can achieve this in IPFW.

Listening outside ipfw / program interface to ipfw
Hi,
Two quick questions that I can't seem to find answers for using google.
1) is is possible to listen outside an ipfw firewall - that is have
ethereal record the packets before ipfw starts dropping them? If so how?
2) Is there an api to ipfw that will let me manipulate rules, query
stats etc? I need something faster than running the command line binary?
Thanks
John

improve ipfw rules
>> 3. I'm intrested in blocking kazaa/P2P trafic with IPFW any help in this
issue
you could possibly block connections at known p2p ports.
deny tcp from any to any 6699 step
but most of the newer protocols use dynamic ports and in turn, are
configurable.
so ipfw isn't exactly ideal on it's own for this.
