While I was attempting to debug a little bit, I installed tcpdump to see if it was even seeing the router advertisements...Apparently it was..

On top of that, if you keep tcpdump running, IPv6 works fine!

I noticed that when I had it manually configured, whenever any sort of routing was necessary, a neighbor solicitation was sent out, but never made it to the other end. However, if I let it auto configure, it worked fine, and as well if I added on the secondary addresss using "ifconfig eth1 add ....", so, with that being said, is it a MAC or IP address filtering problem?

Any ideas would be appreciated, I'd like to get this running, as I'm a big fan of IPv6... I have 1 IPv4 address, but a whole /48 to work with. :-D

Thanks again,
-Matthew Drobnak

tcpdump keeps ethn in promiscuous mode. Maybe this is what was expected?

Smells like a multicast bug in the network driver/card.

An userland way to find out is to check if networking works as expected if he's running other programs that keep the network in promisc mode, like nmap.

or ifconfig eth +promisc?

Real programmers use COPY CON PROGRAM.EXE

Seems I been a little uneasy about it... However, we're expecting any answer from that guy. (At least I am)
