Untangle Option 66

[JoelM]

I will be install a new Untangle firewall for a customer. The manager of the voip phone system said:

Since the phones are cloudfone. Just move the phones over and on firewall put DHCP option 66 with string 'xxxx.xxxx.biz'. (He provided the web address I just removed it)

The information I have found is a little confusing to me. Seems there might be 2 possible places to to add this and 2 different syntax statements. Does anyone have help on this?

Config -> Network -> Interfaces

Edit the interface that has the LAN IP and associated DHCP range you want to add these directives to.

Hit the DHCP Configuration sub-tab, at the bottom is a DHCP options section.

Add one: Description is up to you! The "value" in this case is very specific:

66,"ip or url target passed here"

No spaces.... I have a URL in there with port number and everything to enable my 3CX to autoprovision. *warning* a typo in the above will cause DNSMasq to crash, this removes DNS and DHCP from Untangle. So if you're curious about syntax... just do a DNS lookup against Untangle, if that works at least the service is running.

Otherwise SSH into Untangle and run

service dnsmasq status

But you shouldn't need to that far in unless you're doing something crazy, just be careful and don't put any spaces in that option line.

@Sky-Knight
Thanks. That's what it was looking like but wanted to make sure. Also thanks for the heads up about doing the DNS lookup to verify the service is running.
