Hi.

Thank you, Simon and "john doe" for your responses. I forgot to fix the mailing list options to get individual emails, only digests, so I can't respond individually.

I've inserted my responses below, prefixed with >##. I should also add that I installed and tested my setup with isc-dhcp and everything works as as it should, with the appropriate interfaces serving the right IP addresses. So this is definitely a dnsmaq or dnsmasq.conf issue. I wanted to use dnsmasq primarily because I've used it before, for DNS, and I needed a dynamic DNS update mechanism.

Thanks again for your help.

Sam

Giving some hints more than an answer.

Hi.

I'm running dnsmasq as the local DHCP server in a container/VM/jail
intended to serve as a router for multiple VMs, and the router VM is set up
with multiple vnics, each on a different subnet.
I'll assume that you are talking about VLAN/alias interface.
>## They're actually virtual interfaces, and not alias IP addresses assigned to the same (virtual) hardware network card.

vnic1: Subnet A -> 192.168.11.0 (external)
What Ip are you realy getting on this interface?
>## As indicated, I'm getting 3 IP addresses.
vnic2: Subnet B -> 192.168.21.0 (internal)
vnic3: Subnet C -> 192.168.31.0 (storage)

The problem I'm having is that as soon as a VM on subnet A requests a DHCP address, dnsmasq will not respond to any future requests from VMs on subnet
B or subnet C. If I restart the dnsmasq service, and if the first DHCP
request is from subnet B, it won't respond to queries from subnet A/C. Etc.

Does your network topology works without dnsmasq?
>## Yes
Is this peculiar to the particular version of dnsmasq-2.86? I've tried
everything, with and without option bind-interfaces, with and without all
interfaces explicitly listed, exclude-interfaces, etc.

See above point.

Any help on this would be greatly appreciated. I've already spent 2 days
trying to figure out what was going on. I'm trying to set up
containers/VMs. The problem I face is that once I set up a VM on one
subnet, VM creation fails for all other subnets. A restart of dnsmasq
doesn't help, because then dnsmasq responds to the first and subsequent
DHCP requests from a subnet, but stops responding to VMs on other subnets.

Thanks very much.

Try to get this working with one internal and one external interface.

Same points as for the other subnet.


If I may, find a simple network example for two interfaces
(internal/external), then get dnsmasq working and build up from there.

What netmasks are set _in_the_kernel_ for net1, net2 and net3? The fact
that you've set the netmasks as dhcp-options makes me worry that they
may not be set correctly, as if they are you wouldn't need the
dhcp-options, the correct value would be sent automatically.

You have log-dhcp set. Posting the resulting logs here might be useful.

Simon.

>## Hi Simon: netmask is the same as here, 255.255.255.0, as for the primary IP. I've intentionally kept it the same since I'm testing a simple network topology to begin with. I'm running illumos OmniOS and crossbow for network testing, using a zone (container) with multiple virtualĀ  interfaces, where this zone's role is to be a firewall and router between the different subnets. Firewall is turned off, NAT is working OK. I tested NAT by creating VMs with static IP addresses for different subnets. The DHCP log is attached. As I mentioned above, you can't really see what's wrong since nothing shows in the log once dnsmasq offers an IP address any any interface and stops responding on other interfaces until I restart the service.

Thanks again.
