Hi Everyone,
This is the first time i write a message here and maybe this is not the place,
if i should write this in a forum please let me know…
I am an very happy user of pfsense but right now i have a little problem, i
explain you :
I’m using the last stable version.
I have dhcp server
Just a hunch. Did you by any chance drop udp port 137/138 traffic between
client and dhcp server? As in, is this traffic allowed? Try tcpdump and
check for requests from a problem machine. You might block something win7
has decided it needs. MS tends to have strange/unexpected needs ;)

Hi
What happens (only for the win7 hosts, other are perfects, bad win7 nasty
nasty) after a few second, and especially when you launch i.e. win7 seem to
make some kind of new dhcp request
Just a hunch,
On the Windows 7 machine, go into Control Panel = Internet Options =
Connections Tab = Lan
Well thank you for your answer, this is exactly the same result that when i set
the option 252 with null parameters in the DHCP
(WindowsProxyAutodiscoveryDetection)
But this is workaround, the real question is why the dhcp server is not
providing the rights settings ?

Tcpdump and you will know the answer to that.

i’m so sorry but i don’t see the answer…
1. I put off 252 option from dhcp server
2. I made ipconfig /renew on the host then check the settings where corrects
3. launch i.e. then press random buttons, the close
4. i made ipconfig /all and can see parameter are back to bad ones
If you can
Grab the packet containing the dhcp request/reply that breaks the win7
client. Wireshark will help you analyze this properly. Sorry, cant help you
more then that.
Feel free to post a raw dump of the packets that breaks win7 and I'll take
a look.

I have the packet that gives the wrong informations but i don’t know how to do
a dump raw…
Maybe you can understand this ?
