Hi

I'm using below json on my dhcpv4 setup but found bngblaster is always sending icmpv6 which caused session can not be in eastablished state. is there any option to disable sending the icmpv6 ?

But you still have IPv6 enabled for client 1, which per RFC triggers ICMPv6.

I simplfied the json file with one outer range as below but still can see icmpv6.

"access": [

}
]

Let me try to reproduce and maybe fix.

You set "ipv6": "false", instead of "ipv6": false,.
