It is possible, that your environment contains an rtadvd which supplies
an autoconfigured IPv6 address, and a route that goes to nowhere. Does
"ifconfig -a" show IPv6 addresses with 2001 or 3ffe prefixes? What does
"route -n get -inet6 default" say? If you have such a bogus route, you
can get immediate relief with "route -n delete -inet6 default".

With no route at all, the application should fail over to IPv4
immediately, but it may take longer to detect a broken gateway.

I actually run a bogus "rtadvd" on purpose, since IPv6 does work fine
one the LAN; it's just that all I can get outside of it are horrible
tunnels. I configure the clients like so:


--- /etc/ifconfig.fxp0 ------
up
!echo
!dhclient -q $int
!rtsold -f -1 $int
!route delete -inet6 default
