Description

I'm attempting to enable Network Booting from a UEFI HTTPBoot URL on one of my VLANs.

I can enable network booting and set the next server, default BIOS file name, UEFI file names, etc and it works perfectly. When I attempt to provide a value for the UEFI HTTPBoot URL, the DHCP Server fails (complaining about an "unknown option").

Relevant system logs:

NOTE: Affected Architecture should be SG-1100, arm64 (not amd64), I selected the wrong one.

Interestingly, this issue does not arise if the UEFI HTTPBoot URL is enabled on the default LAN interface DHCP Service (i.e. not on a VLAN). Here is the resulting config, which works as expected without raising a config error:

...
    option tftp-server-name "192.168.XX.XX";

    option custom-lan-0 "HTTPClient";
    next-server 192.168.XX.XX;
    if substring (option vendor-class-identifier, 0, 10) = "HTTPClient" {
        filename "http://192.168.XX.XX:XXXX/boot.ipxe";
    } else if option arch = 00:07 {
...

So apparently custom-lan-0 is a supported option but custom-opt3-0 is not? Unfortunately I'm not familiar enough with this configuration syntax to understand why they would be treated differently.
