For the past couple weeks I tried configuring an AWS Instance to be reachable via IPv6. However I can't seem to connect to this Machine (Ubuntu Server 16) using an SSH Connection.
Heres what I did so far:
I created a public VPC with an IPv4 and IPv6 CIDR Block.
Therein lies a subnet with autoassigned IPv4 and 6 Adresses
I created an Internet-Gateway (IGW) and had the routing Tables point all outgoing traffic to it: Routing Table
I set up the ACL to allow ALL incoming SSH Traffic: ACL
Now, while I can access the machine unsing it's public IPv4 Adress and DNS-Name, I can't establish a connection via IPv6
Am I missing a step in configuration or is IPv6 not fully supported in my AWS Region yet? (eu-central-1)
The Instance does have an IPv6 Adress and it's security group allows inbound SSH Connections:
Yet whenever I try to connect to it via its IPv6 adress, I get a "Network is unreachable" Error
