Hi all,
I saw some time ago a similiar question on the mailinglist but the
relevant config files were on a temporarly server, so I can't
reconstruct the situation. So I hope someone could say the things a
second time ;-)
Here is my setup:
I'm running a FreeBSD server behind a DSL-Box (NAT) with one network
interface. This server is connected with two other workstation
through a switch. I register by sixxs (a IPv6 service provider).
After some installation I got my IPv6 connection between the sixxs
provider and my FreeBSD server running! I can ping www.kame.net and
when I go to ww.kame.net with lynx I "can see" the dancing kame. So
the setup should be fine. I setup rtadvd for the workstations and it
seems to be ok. The workstations get their IPv6 addresses but I can't
ping anything outside my LAN.
Summary:
Connecting to the IPv6-world from the FreeBSD-server is OK but I
don't get any connection from the clients.
Here are the configs:
/etc/rc.conf
ipv6_enable="YES"
ipv6_defaultrouter="2001:6f8:900:612::1%em0"
ipv6_default_interface="gif0"
gif_interfaces="gif0"
gifconfig_gif0="192.168.130.2 212.224.0.189"
ipv6_ifconfig_gif0="2001:6f8:900:612::2 2001:6f8:900:612::1 prefixlen
128"
ipv6_gateway_enable="YES"
ipv6_ifconfig_em0="2001:6f8:900:612::3 prefixlen 64"
rtadvd_enable="YES"
rtadvd_interfaces="em0"
/etc/rtadvd.conf

I don't have an more ideas! I always thought the problem is the
server behind the NAT but the surfen and ping'ing from the server
itself is no problem, so I think the problem must be somewhere else?!
Best regards,
Stefan
