I am seeing this same thing on my core router cluster. It's the
DHCPDISCOVER followed up with DHCPOFFER that never gets a DHCPACK. I
have a single customer with a router made by Hon Hai Precision (I think
it's a Vonage something or other) that will now not get an IP address
after upgrading to 6.1 on Sunday. Everything was working fine with 6.0
up until now.

6.1 dhcpd

[Bastien Durel]

Hello,

Since I upgraded to 6.1, my printer does not get its IP from dhcpd
anymore.

Printer is a xerox phaser 6022.

dhcpd gets dhcp requests and reponds to it (I've show packets with
tcpdump, and here are the logs)

I've connected the printer to a linux laptop with dhcpd, and it got the
address it recieved from it.

Here is the openbsd tcpdump trace :

And here is the Linux tcpdump trace :

Do you know what change may have introduce this ?
