dnsmasq: dhcp doesn't return netmask

Hello Barnabé,

Did you try it without explicitly seting the netmask?

dhcp-range=192.168.1.97,192.168.1.110,10m

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.


1. Exerp or 'shorewall show'
------------------------------------------------------------
------------------------
Chain OUTPUT
 9 2952 ACCEPT udp  --  * eth1 0.0.0.0/0 0.0.0.0/0 udp
dpts:67:68
Chain eth1_in
15 6656 ACCEPT udp  --  *   *    0.0.0.0/0 0.0.0.0/0 udp
dpts:67:68


2. Content of LRPs config:
------------------------------------------------------------
------------------------
LRP="root config etc local modules libcrpto libm libz
log dropbear
ulogd iptables shorwall  ppp pppoe  ntpdate ntpsimpl
dnsmasq"

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

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
bib
