Hi,
If you don't want the "hostile users" know that you are shaping their packets 
in the way to Internet, you might want to make use of the Bridge facilities in 
OpenBSD.

There you can tag the packets merely based on their MAC, and then in higher 
layers have "pf" deal with those packets as you wish!

Regards,
Amir

Subject: pf by mac address?

Hello all,

Perhaps I'm looking for this the wrong way.  My local network now (and
hopefully temporarily) includes hostile users.  I may need to exercise
controls on their Internet usage by machine.

Now, I can certainly tell dhcpd to give certain machines certain IP
addresses by reference to their MAC address.  But that won't stop
these users from allocating their own IP address and essentially
bypassing dhcpd.

The environment includes a lot of wireless -- most users connect this
way.

So I'm thinking I'd like to be able to write packet filter rules based
on MAC address.  I'm not necessarily going to want to simply cut off
all their Internet access, but pf offers a lot of options to do what I
think I might want to do, if I can make rules by MAC address.  Traffic
shaping and additional rules about what ports they can access come to
mind.  Possibly other possibilities will come to your mind --
hopefully you see what I'm thinking.

Is it possible?
