Hello to all and happy new year. I have a problem with my ipv6 and zone based firewall implementation. I have a cisco 1841 with dual stack ipv6 implementation. If i do not implement ZBF all works fine. On the other hand if ZBF is on the ethernet interface of the router and the pc's behind it do not get ipv6 addresses. The router gets an ipv6 address normally and communicates with ipv6 sites with no issue.
