OT, ip6tables rules for radvd

[Kirk Reiser]

Hi Greg: I really don't know if me sticking my nose in will be helpful
or not but why do you need to do this?  Are your machines on different
subnets or something?  On my network other than configuring
/etc/radvd.conf I didn't need to do anything.

OTH, if you wish to pass packets through an interface you also need to
accept forwarding, could that be what you're missing?
