Good afternoon-

This is in regards to pfsense-2.1.4-RELEASE.

This morning my ISP (finally) turned on IPv6 on our circuit. They
assigned a /126 P2P link for the WAN and are routing a /48 to us. I
have the WAN interface configured without issue, and am able to ping6
from the router itself to external addresses.

The problem arose when I added the static IPv6 configuration to my LAN
interface. I chose an arbitrary /64 subnet for the LAN and assigned an
IP to the interface. When I applied this configuration, *all* traffic
to and through the router (both v4 and v6) stopped. I couldn't ping
the v4 address of the router, etc. I ended up having to attach to the
serial console and restore a previous config file in order to restore
connectivity.

My questions are:

1) How was adding v6 addressing information to the LAN interface able
to affect v4 traffic?

2) How can I add static v6 configuration to the LAN interface sucessfully?

This all seemed like it should be a very simple task, but apparently
I'm missing something.

Thank you!
-Erik
