IPv6 clusters support for import in rancher

We have a mix of IPv4 and IPv6 clusters which we import in Rancher to administer. The issue is with IPv6(dual stack clusters, services and pods IPv6 addressing) is that long tcp commands, where Rancher creates a consistent chasnnel to API server, are not working because of IPv6 addressing. Commnads like kubectl logs, kubectl exec, helm etc. Is there a way to make these work.
