This sounds like broken path MTU discovery.

The whole machine, or just the network connection? I've never seen a whole machine hand - I have seen delays connecting to machines that do reverse DNS lookups on 6to4 address, as the reverse tree for 6to4 hasn't always been in great shape. > Performance has also been poor compared to IPv4. Like any sort of tunneling, 6to4 can suffer from senic routing. Several of our local ISPs run internal 6to4 routers, which helps. David.
