I'm really stumped as to how ipv6 could partially fail like this only on specific apps. Seems like it should either completely work or completely fail.

Anyone have any idea what might be happening here and/or how to fix?


Hi David,

If ping works, but bigger packet things don't, then you might have some PMTU
issue that is only affecting IPv6. You can confirm this with a tcpdump trace
quite easily. Look at the packet sizes. Both things you've mentioned (opening a
web page and updating antivirus) are http, and it does usually use the maximum
transmission unit.
