Hi Brendan,
Have a look at https://dhcp.isc.org as it is able to convert all of
the ISC DHCP config snip you posted:
{
# UBNT stuff
/// This configuration declares some subnets but has no interfaces-config
/// Reference Kea #245
"Dhcp4": {
"option-def": [
{
"space": "ubnt",
"name": "unifi-address",
"code": 1,
"type": "ipv4-address"
}
],
"client-classes": [
{
"name": "ubnt",
/// from: match if (substring(option
dhcp.vendor-class-identifier, 0, 4)) = 'ubnt'
"test": "substring(option[60].hex,0,4) == 'ubnt'",
"option-data": [
{
"space": "dhcp4",
"name": "vendor-class-identifier",
"code": 60,
"data": "ubnt"
},
{
"name": "vendor-encapsulated-options",
"code": 43
}
],
"option-def": [
{
"name": "vendor-encapsulated-options",
"code": 43,
"type": "empty",
"encapsulate": "ubnt"
}
]
}
],
"subnet4": [
{
"id": 1,
"subnet": "192.168.248.0/24",
"option-data": [
{
"space": "ubnt",
"name": "unifi-address",
"code": 1,
"data": "192.168.248.1"
}
]
}
]
}
}
Thank you,
Darren Ankney
