The custom DHCP options are currently all added as text type. This doesn't work for many options, which require a different type. e.g. option 2 must be 'integer signed 32'.

To resolve, we need a drop down box added for each custom option to select the type. The possible options are:

integer unsigned 8
integer unsigned 16
integer unsigned 32
integer signed 8
integer signed 16
integer signed 32

Note for some of these types, the data is not enclosed in quotes, such as integers for one.

There are a couple other types, but not ones we're concerned with at this time.

Functions on Mon Nov 1 15:45:03 EDT 2010 firmware. Tested with "1(" for a Motorola TEAM phone which grabs Option 43 - vendor specific information from the DHCP server.

This is handy, thanks for the request and thanks to the developers for adding it!

One issue with this on the integers. It's putting int8, int16, uint8, etc. into dhcpd.conf file which is invalid syntax. It has to be exactly as listed in the original ticket, rather than 'int8', 'integer 8'. 'uint8' must be 'integer unsigned 8'. etc.

This fix/feature worked just fine with the Sun Dec 5th 07:23:23 EST 2010 nanobsd snapshot.

I added one option of each type to my lan dhcp config, and the results in the dhcpd.conf file are as follows.

option custom-lan-0 code 128 = text;
option custom-lan-1 code 4 = string;
option custom-lan-2 code 5 = boolean;
option custom-lan-3 code 6 = unsigned integer 8;
option custom-lan-4 code 7 = unsigned integer 16;
option custom-lan-5 code 8 = unsigned integer 32;
option custom-lan-6 code 9 = signed integer 8;
option custom-lan-7 code 10 = signed integer 16;
option custom-lan-8 code 11 = signed integer 32;
option custom-lan-9 code 12 = ip-address;
option custom-opt1-0 code 2 = text;

default-lease-time 7200;
max-lease-time 86400;
log-facility local7;
ddns-update-style none;
one-lease-per-client true;
deny duplicates;
ping-check true;
subnet netmask {
        pool {
        option routers;
        option domain-name "";
        option domain-search-list "";
        option domain-name-servers;

        option custom-lan-0 "VLAN-A=100;";
        option custom-lan-1 "Test string";
        option custom-lan-2 true;
        option custom-lan-3 6;
        option custom-lan-4 7;
        option custom-lan-5 8;
        option custom-lan-6 9;
        option custom-lan-7 10;
        option custom-lan-8 11;
        option custom-lan-9;

Looks correct to me.
