My -stable machine just turned deaf on its gif0 interface.
I can see the encapsulated packets coming in and out and they
look correct...

12:18:25.138253 205.178.90.194 > 204.123.2.236: 3ffe:1200:301b::1 > 3ffe:1001:1:f001::2: icmp6: echo request (encap)
12:18:25.191209 204.123.2.236 > 205.178.90.194: 3ffe:1001:1:f001::2 > 3ffe:1200:301b::1: icmp6: echo reply (encap)

but the replies never make it into gif0, so far as I can see.

/etc/rc.conf has:

ipv6_enable="YES"
ipv6_network_interfaces="lo0 de0"
ipv6_prefix_de0="3ffe:1200:301b:0"
ipv6_gateway_enable="YES"
ipv6_static_routes="default"
ipv6_route_default="default -interface gif0"
ipv6_router_enable="YES"

gif_interfaces="gif0"
gifconfig_gif0="205.178.90.194 204.123.2.236"

What happened? :-)
