I am in the process of moving my phone system DHCP from my Mitel 3300 to a
FreeBSD so I can parse the DHCP file. In order to make Mitel's option 125
work correctly, I have to specify some vendor specific options. I believe
this is option 124 if I understand the Mitel documentation correctly.
We have a Mitel 3300 and use OpenBSD servers with the ISC DHCP server.
We have 5212 and 5224 IP phones and 5550 IP consoles. The consoles
are the trickiest of all to get working with DHCP. Below are the
sections from our DHCP config that relate to the Mitel. A few things
to note about it. 10.1.254.254 is our name server and dhcp server.
10.1.5.1 is the IP of our Mitel 3300 controller/server. the
/sysro/e2t8260 is the path of our e2t. The two most key components to
get it to work are the option-128 and option-129. You need to set
these as the hex representation of the IP address of your Mitel
controller, so in our case, 10.1.5.1 became 0A:01:05:01. It won't
work otherwise. 10.1.254.255 is our VPN gateway to our other office.
The vendor-class-identifier for mitel phones is always null (at least
for the 5212, 5224, and 5550 consoles). We use this to separate the
Mitel phones into a separate class so they are in their own IP block.
We originally just used the vendor-class-identifier thing, but then
started to find NICs that had vendor-class-identifier = null, so I
noticed that all of our Mitel device MAC addresses start with
1:08:00:0f., so we use that to separate them as well. It is a bad
hack, but it works for us. Anyway, with this config, we have 5212,
5224, and 5550 consoles getting their addresses with DHCP. Feel free
to contact me if you have any questions.

Can someone point me in the right direction?
For the ISC DHCP server, here's an example for setting option 252 for
auto-proxy config:
option wpad-url code 252 = text;
subnet _yournetwork_ netmask _yournetmask_ {
option wpad-url http://proxy/proxy.pac;;
...
}
You'd need to choose your own option name for option code 124, and a
type (probably string), and then set whatever config you need in that
option statement...

How about:
netstat -rn -f inet | grep default | awk '{print $2}'

Wouldn't that just get his router's internal NAT address?

Re: dhcp question
If you're running dhcpd(8) on two interfaces, the command should
probably be
/usr/sbin/dhcpd -q rl1 rl2

Hi all
I would like to configure 2 network cards to have dhcp server function
but it doesnt'work
NIC rl0 is WAN port
NIC rl1 is for 192.168.0.1 network
NIC rl2 is for 10.0.0.1 network
I put dhcpd.sh in the /usr/local/etc/rc.d
#!/bin/sh
/usr/sbin/dhcpd rl1 -q
/usr/sbin/dhcpd rl2 -q
Those rl1 and rl2 are using NAT to go to outside
In the /etc/dhcpd.conf
I configured the network
authoritative;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.100 192.168.0.150;

option broadcast-address 192.168.0.255;
