Hi @JS Kim ,
Currently AVS doesn't support IPv6. Can you drop an email to msrini@microsoft.com with your end to end scenario and your AVS Resource ID and your company name ?
This feature on AVS depends on IPv6 support by Azure 1st party services like Azure Firewall. With the PIP on NSX based Internet enablement feature, we will need to check whether this can be accommodated or not.
