Pfsense 2.2 Interface advanced dhcp client configuration

clw

For some ISP's in Switzerland we need to set DHCP option 60 (dhcp-class-identifier) to receive a ip on wan interface.

In the older pfsense versions i set it directly in the /etc/inc/interfaces.inc file like this:

$dhclientconf .= <<<eod<br>interface "{$wanif} {
send dhcp-class-identifier "100008,0001,,pfsense dhclient 2.1";
…

Now in pfsense 2.2 i want to use the new possibility in the web ui. interfaces --> wan --> DHCP Client Configuration --> Advanced (checkbox) --> send options

i put this in the textfield:
dhcp-class-identifier "100008,0001,,pfsense dhclient 2.1";

But i do not receive a ip address.

What syntax do i have to use in the web interface?
Do i have to use the Delimiter (space, colon, hyphen, or period) (omitted for none). to make it work?</eod<br>

Now I spend again some time on this issue.

I Checked the log with Wireshark and now i know the problem.

The problem is that pfsense web gui do not accept a "," (column) in the text field of dhcp-class-identifier.

If i put this in the Advanced Config of the WAN interface (Web UI):
dhcp-class-identifier "100008,0001,,pfsense dhclient 2.1"

The output (in Wireshark) is:
100008;\n\tsend 001;\n\tsend ;\ blabla

The columns (,) are replaced with ";\n\tsend".

Is there any way to put a column in the field? Or e escape code etc.?

Apparently not:

https://github.com/pfsense/pfsense/blob/RELENG_2_2/etc/inc/interfaces.inc#L3858
https://github.com/pfsense/pfsense/blob/master/src/etc/inc/interfaces.inc#L4164

Appears completely misimplemented, just file a bug perhaps.

Ok. Thank you for this information.

Do I have to create a bug report or something else?

Well yes if you want that fixed.

Try using the config file override option to specify a your custom DHCP client config file to use.
