Hello all,
I've been toying with getting IPv6 installed and running for a
while, and I've got only one hurdle remaining.
I have 5 servers on my quaint little network, and my primary
firewall is configured with an IPv6 address, we'll say
1000:2000:1::6 and is connected to my ISP through a gif tunnel
(router doesn't support IPv6 yet, on my end) to 1000:2000:1::5. I
can ping6 all day long across this tunnel, and I can even connect
through this firewall to other sites using the IPv6 addresses.
I've been given 2001:4900:1:0111::/64 for my use. I've configured /
etc/rc.conf on my first two machines with ipv6_enable="YES" and
given them 2001:4980:1:0111::1 and 2001:4980:1:0111::2. Each
machine can ping6 itself, but they cannot ping6 eachother. I know
the copper is good, and my ipv6 is running along side my ipv4
addresses and such. In addition, there are no firewalls in between.
Is there something I'm missing?
Also, what the heck is rtadvd_enable="YES" actually doing for me?
I understand it's broadcasting some routing stuff so my other hosts
can auto-configure their IPv6 addresses, but anything else?
Thanks a lot all!

Alright, sorry to reply to my own post, but the situation is a little
different than I thought. As it turns out, all of my systems can
ping eachother, save my gateway/firewall machine. This machine is
configured with 2 NICs, with ethernet bridging. My configuration is
as follows:
INET -- ROUTER -- FBSD GATEWAY -- LAN
While the FBSD GATEWAY has an IP assigned to it's internal interface
(available from both sides), and it's bridging IPv6 correctly, I'm
thinking this may be my IPv6 problem. The gateway has a gif tunnel
to my ISP for IPv6 routing, as my cheap router doesn't support the
new IP protocol. The gateway can ping across the tunnel using IPv6
perfectly fine. It can also ping it's own IPv6 addresses, regardless
of the interface. What I CANNOT do, is ping to the IPv6 box from any
machine on my LAN. I can ping IPv4 just fine.
Please help!
