	it may be that you need to start everything from scratch (reboot
	preferable), because you may have path mtu discovery results staying
	in routing table.

	could you show me the result of:
	ifconfig -a
	netstat -rnl
	ndp -i gif0

>Hmm, should three actually be a /dev/gif0 or is it just a logical device?

	no.  network interfaces are not present in /dev.
