- Thread-Topic: RE: DHCP not blocked
Sorry, pls. forget the earlier picture and description. But I guess I
got the answer from Camiel Dobbelaar, but not too sure though.
Hope the picture comes right. Infact the picture was wrong
------------ | OpenBSD |
|DHCP Client |-------|DHCP System |
|Windows PC | fxp1 |Server |fxp0
Rules for PF:
block in quick on fxp1 all
block out quick on fxp1 all
Now to answer questions from others:
> How are you invoking dhcpd?
DHCP server on the fxp1 interface on the OpenBSD 3.2 Stable system.
(cmd: dhcpd fxp1)
> How are you invoking the dhcp client?
A Windows PC on the fxp1 side.
I was sure that tcpdump gets the pkts before PF gets it, didn't feel
that dhclient would do that too. Now it makes sense.
Pls. let me know if it is not what I think.
Thank you all

Stupid question, but maybe worth a shot: Do you have the dhcpd bound to
fxp1 interface (/etc/dhcpd.interfaces) ?
