We’re building a IPv6 only lab and need GenieACS to listen on IPv6. It does not seem to do this by default. Does GenieACS support pure-IPv6 only? The environment variables make no reference to IPv6 so I’m trying to verify if IPv6 is a possibility or not.

Nmap scan report for 2605:9fc0:dc1::11  
Host is up (0.0045s latency).  
All 101 scanned ports on 2605:9fc0:dc1::11 are closed  
Nmap scan report for 172.82.24.11  
Host is up (0.00053s latency).  
Not shown: 98 closed ports

PORT STATE SERVICE  
7547/tcp open cwmp  
7557/tcp open unknown  
7567/tcp open unknown

We can setup a NAT solution if IPv4 is the only option. The CPE devices are all 100% IPv6 only.

I had it in a docker container for testing purposes.  
There IPv6 somehow worked.  
At work I am running genieacs behind a nginx, but the server is IPv4 only. It is behind the cgnat so it is not a problem to reach the CPEs.

But I will have a look at IPv6.

This setting is needed in the env file: GENIEACS\_CWMP\_INTERFACE=::  
The nodejs will run in dual stack mode.  
This has to be changed for fs service to, with the correct env setting.  
I had no problem, connecting over IPv6 to my CPE. The DNS name for this server was ipv6 only.
