Re: IPv6 problem after 6.3 upgrade

i tryed 4 different IPv6 hosts and none of them are reachable from the
6.3 machine. From a different 6.2 machine in the same rack i can reach
all of the addresses via IPv6.

Here are the traceroute6 outputs:
> traceroute6 2a00:1450:4001:811::200e
> traceroute6 to 2a00:1450:4001:811::200e (2a00:1450:4001:811::200e), 64 hops max, 60 byte packets
