Possible bug in Untangle v11

I've been up way too many hours to make this formal, but here goes nothing.

Code:

---

# Interface 2 (eth1) DHCP
dhcp-range=interface:eth1,10.0.1.50,10.0.1.250,3600
dhcp-option=tag:eth1,3,10.0.1.1 # gateway
dhcp-option=tag:eth1,1,255.255.255.0 # netmask
dhcp-option=tag:eth1,6,10.0.0.11 # dns
dhcp-option=tag:eth1,6,10.0.0.11,10.0.1.1 # custom dhcp option

---

Historically dnsmasq would take the last line of a given configuration and run with it. In this server's case it was only going with the first one.

dhcp-option=tag:eth1,6,10.0.0.11 # dns < this is what the clients are getting

Not dhcp-option=tag:eth1,6,10.0.0.11,10.0.1.1 # custom dhcp option

Bit of a problem, I'm working around it now obviously, but bit of a problem. I'm going to see if I can duplicate this in a lab tomorrow.

I've replicated this condition in my lab.

Creates the following /etc/dnsmasq.conf, just like it's supposed to.

But sadly, here's what the client gets...

So we can't refine option 6 anymore, I suggest Untangle allow a comma separated values to be put in the DNS Override box, we just won't be able to do option 6 changes in the DHCP options section.

Also, minor UI problem. The "Edit interface" subwindow won't resize with the browser.

Untangle 10 has dnsmasq 2.55-2
Untangle 11 has dnsmasq 2.62-3+deb7ul

Something between those versions changed.

We will investigate.
Thanks!

Thanks Rob!

...and I just figured out that Android devices 'need' this, since they always use Google DNS as a secondary, if none is provided.

As far as I know that "interface:eth1" is supposed to be "tag:eth1" like the rest of it.

sorry, Rob - you read the post before I deleted it. I logged it into bugzilla, instead. The way it is works until the next kernel. I didn't want give the impression it is broken, or will break anytime soon.

But you are right:

a tag whose name is the name of the interface on which the request arrived is also set.
