In IPv4 Im trying to use the circuit ID as the identifier to restrict IPv4
leases to one IP address at bridged clients.
However, some clients have phone service and we put a GrandStream ATA as a
bridge after their ONU but before the router.
The ATA does pull from its own shared pool for IP leases, but it grabs that
circuit ID and stores it in the lease table, not allowing anything else past it
to obtain an IP address
Im trying to do an if statement in the “identifier-expression” under the
flex_id hook to swap it out.
This is what I have.. Im sure it's a syntax issue or something along those
lines. But Im hoping that it's possible to do something like this:
{
"library": "/usr/local/lib/kea/hooks/libdhcp_flex_id.so",
"parameters": {
// "identifier-expression": "relay4[1].hex",
"identifier-expression": "if (substring(option[60].hex,0,18) == 'HT8XX
dslforum.org' or substring(option[60].hex,0,18) == 'HT802 dslforum.org' or
substring(option[60].hex,0,18) == 'HT812 dslforum.org') {option[60].hex,0,18}
else {relay4[1].hex}",
"replace-client-id": true
}
},
Any help would be great
Thanks!
