Hi!
In general it is a very bad idea to use the same way what you have been
using before when you are moving to a new platform. You wouldn't use bash to
manage win2k8 servers, just to give you an example what I am talking about.
The question is:
What do you want to do with pf. Forget about netfilter/conntrack and so on.
What do you want to achieve?
This is the only question.

I believe you are righ istvan!
this is the thing:
I want to make some traffic shapping on both interfaces of a freebsd box.
As u all probably know the real congestion occurs generally on the
downlink interface because of the asymmetric nature of some protocols
(eg. http)
on the internal network i have some applications that puts dscp tags
to packets according to different classes of service. the uplink
shapping can be done simply by mathing the corresponding dscp field of
each connection and sending to different queues. (by the way the doc
i´ve read only presents TOS mathing and nothing about dscp)..
anyway , the problem arises when the incoming traffic (from the
internet) has no dscp tags and i need to enqueue then accordingly to
make the downlink traffic shapping.

Hi folks!
I´m trying to figure out if there is a way to make connection marking
in
a
similar way as the iptables´s CONNMARK target does?
Does pf supports this feature?
My intentions are to tag an outgoing packet, transfer the tag to the
hole
connection and then use that tag to mark incoming packets belonging to
the
same connection.
Also, i would like then to use that mark to enqueue marked packets to
hfsc
clases.
I´ve done all of this in linux but never on freebsd, I´ve searched in
pf´s
man page and the FAQ without success.
thanks in advance,

Hi evelio, see below:
-- cut here --
tag <string>
Packets matching this rule will be tagged with the specified
string. The tag acts as an internal marker that can be used
to
identify these packets later on. This can be used, for
example, to
provide trust between interfaces and to determine if packets
have
been processed by translation rules. Tags are "sticky",
meaning
that the packet will be tagged even if the rule is not the
last
matching rule. Further matching rules can replace the tag
with
a
new one but will not remove a previously applied tag. A
packet
is
only ever assigned one tag at a time. Packet tagging can be
done
during nat, rdr, or binat rules in addition to filter rules.
Tags
take the same macros as labels (see above).
tagged <string>
Used with filter or translation rules to specify that packets
must
already be tagged with the given tag in order to match the
rule.
Inverse tag matching can also be done by specifying the !
operator
before the tagged keyword.
-- and here --
Anyway, I believe that keeping state for the desired outgoing
connections should be enough all by itself. You would simply add the
Indeed no, what i want is also to mark the connection to be able then
to mark incoming packets beloging to the same connection.
"queue <queue>" directive at the end of your pass out rule, even
though the interface packets go out through is the "external" one, and
you want to do shaping on the "internal" one but, as I understand, for
that you also need floating (not if-bound) states. If I'm wrong, I'd
i am not sure what you mean with "floating (not if-bound) states"
could you please explain this.
like somebody with better pf knowledge to correct me :)
pf(4) is not iptables. So before using it read more about it.
I´m aware of that.
I think its pretty obvius that my post is simply trying to figure out how
to achieve with pf something that i use to do with netfilter.
I´ve read this before but nothing comes up to me.
