Yes, if you enable forwarding you probably should have some rules
constraining it's usage. Can't do that in 2.2 kernels though so this is
the best option..
Really all it allows is source routing which I don't think is a security
problem on the open internet.

Cool!
Does it work? :>
I think you need an ip addr del as well to get rid of the 6to4 address
you added..
