Setup:
VM (eth0) -> hostveth -> ContainerVeth
eth0 and hostveth are in VM network namespace while containerveth is in different namespace
sysctl ipv6 forwarding and iptables FORWARD chain are allowed. Checked filter table and no rule to block link local ipv6.
Request coming from outside of VM to Linux pod (container). Pod receives a request from linklocal ip and it responded back to the request with linklocal ip as dst ip . The response reached VM (took tcpdump on hostveth) but its not getting forwarded to VM eth0. This forwarding worked for other ipv6 destined addresses. Please let me know if i'm missing something. Happy to provide more details. Thanks in Advance!
