TomatoUSB

I have two routers with the latest version of Tomato installed.

The main router (hooked to the Modem) is using a IPv6 6to4 static tunnel using he.net.
IPv6 works to clients connected via LAN and WiFi with this router.

On my second router, it is setup as a Wireless Ethernet Bridge. It is working fine with IPv4 via LAN and WiFi
IPv6 is set to manual using the next assignable IPv6 1 address up from the main router local IPv6 address.
From the Tools I can ping the IPv4 address of the Main Router, but not the IPv6 assigned or link-local addresses
Clients get assigned the appropriate IPv6 address but it seems no traffic is passed over the wireless ethernet bridge.

What am I missing? How do I get my IPv6 traffic to flow over the bridge?

I'm not sure, and someone can correct me if I'm wrong. The support for IPv6 is dependent on the either the Wireless bridge drive or hardware. Thats what I've gathered so far from reading posts on the topic. I am only answering my own question for the benefit of others. WDS seems to support IPv6.

I have issues with dropped packets in WDS mode. I lose about 1-2% of packets when I put the routers in this mode. If I run it in AP mode with the Wireless Ethernet Bridge I don't have any dropped packets. I'm now at a loss as to how to fix these issues.
