Can something, anything, ping your IPv6 address of the eth0 port on
gateway1? It might be that he.net does not have a route to your /28
network. When you ping from your gateway, you are using the ::1671
address.
Also does your other machine have a route out to the rest of the
network?
I find tcpdump VERY handy in this situation.
