Hi, Eric
First of all, I appologize for the late answer.
The dnsmasq version used on the gw is the one packaged with BUC 2.4 iso.
For the moment, i doesn't have access to the LAN in question
for tcpdumping what's going on. i hope to report about this point
at the end of week-end. (for this test, i will unplug all clients
from lan except my one just to see what's happend)
Please, notice also: before having discovered the issue in question,
i'm absolutly sure that netmask has been set correctly once or twice
(i saw it). But for an unknown reason, it was gone at next day and i
couldn't got it okay since them. BUC's host was also the only system
servicing dns and dhcp on our lan (for now, those services have been
migrated on another infrastructure (djb+dhcpd)).
kindest regards

Hello Barnabé
I don't see anything obviously wrong in your setup. I'll try to create a
simular setup later to see if I get the same problem.
Can you try to run a packet sniffer (tcpdump, ethereal) on you workstation
or router (tcpdump) to pinpoint why the netmask isn't advertised?
Which version of dnsmasq are you using?
Eric
Hello, Eric
Thank you for your help.
Sorry for late answer but my 'webmail' reply was rejected by server.
I've just tried your tip, removing explicit netmask in dhcp-range.
This didn't resoved this issue.
Furthermore, I've tried following change without any success:
a) added: interface=eth2 no-dhcp-interface=eth2 b) removed:
dhcp-option=1...
(mask)
dhcp-option=28... (broadcast) note: broadcast address still okay
c) removed both eth2 params above
Shorewall dhcp rules seems to be okay and i can ping
any address on the 192.168.1.0/25 subnet from the firewall.

Hello Barnabé,
Did you try it without explicitly seting the netmask?
dhcp-range=192.168.1.97,192.168.1.110,10m

Dear all,
I wonder why dnmasq's dhcp doesn't returns the netmask, which should
be 255.255.255.128
on both LAN and DMZ. Here is the dhcpcd log exerp on my (gentoo-linux)
workstation:
Apr 18 11:39:48 julie dhcpcd[14872]: subnetMask option is missing in
DHCP
server response. Assuming 255.255.255.0
Same thing appens for macOSX systems on the same lan.
Would someone be nice enough in giving me hand for refine diagnostic
and/or resolve this issue ?
Many thanks in advance for your help
Kindest regards
