[Kea-users] Problems with offer from KEA

[egor.grijuc at orange.com]

Hello.
I faced a problem with offering ip addresses from KEA to end user.
Configuration is very simple:1 shared network and matching with suboption 150 of option 82
KEA does matching correctly and offering correct options to client and correct ip.
The only problem is that this offer doesn't reach client.
In the same time on same server if I stop KEA an start simple dhcpd-offer reaches client, you can see in attached file SimpleDHCP.cap that after offer are request and ACK, but in KeaDHCP.cap are only
Dicove-offer and offer doesn't reach client)
The problem is that I don't see any difference between offer from simple dhcpd and kea dhcp.
In attachment are 2 cap files,SimpleDHCP.cap - is packet capture when simple isc dhcpd server runs and KeaDHCP.cap is packet capture when kea dhcp4 server runs.
Can anyone explain me where is the difference?
Below is configuration of kea:
