I have a pfSense 2.2.6 box that is connected with a WAN link that supports native IPv6. IPv6 is working great, and my clients can access IPv6 services on the Internet and also on the local network.
However, I'm unable to ping the clients from the Internet, although I have created an IPv6 rule on the WAN link (and LAN as well) that permits IPv6 ICMP.
Is there anything I'm missing?
