Unable to access an Instance through IPv6
I have got an default Ubuntu instance on the A1.flex flavour which I want to access from outside through IPv6.
I already did the following:
- Added an IPv6 CIDR Block
- Added an v6 address to the VNIC of the instance
- Changed the default routing table for the VCN to enable ::/0 traffic to the internet gateway
- Changed the outgoing security list to enable all v6 traffic
- Added an rule to allow ICMP incoming traffic from ::/0
Still I'm not able to ping the instance. Accessing stuff on the internet from the instance itself works fine (so e.g. I can do "ping -6 google.com"). Accessing the instance from outside via the IPv4 address also works fine. Did I forget to do something on the instance itself or do I need to configure something else on the OCI console?
