I'm having trouble getting the world to see my IPv6 network, and now trouble getting the web bits to test locally.

I think it's because I have essentially the same routing problem with IPv6 as I've got with the IPv4 multi-node routing with multiple Internet connections. The server has one NIC in the /48 address range, and another in the routed /64 from that /48 range. When I try to force IPv6 from a node on my /64 network, I think the server is having trouble sending responses to the right NIC.

I think I'm going to reapply my IPv6 with two /64 ranges instead. I'll release the /48, readdress the WAN network to use the allocated but unused /64 network, and make a second IPv6 tunnel directly to the WiFi network.
