What I don't understand is how this is happening. tcp.mssdflt is set to 1400 bytes and tcp.v6mssdflt is only 1024. If PMTU discovery was working, this should not be a problem. If PMTU discovery is not used, the MSS defaults should keep the packets small enough to work over the tunnel.
Doesn't IPv6 require a minimum MTU of 1280 bytes? Try setting the IPv6 TCP MSS to 1350 or so, bigger than IPv6 code requires, but small enough to fit into the ~1400+ byte MTU effectively available when you tunnel the traffic.
