today. I was using the wrong prefix in my radvd.conf file which was
causing my return traffic to go to someone else's network. At one
point, I had a nasty routing loop which spiked the traffic level.
did get it corrected and I'm now able to ping6 sites. In any case, I've got a basic write-up of it here.
Props to Sysmin and Quigon (The Hacker Pimps) for reminding me about IPv6 and turning me on to OpenWRT. Try to find the PDF of their presentation for a little extra help in playing with the 54G.
