While brushing up my ipv6 knowledge i ran into an issue with sixxs-aiccu
and configuring ipv6 in rc.conf:
I have manually configured my gateway to route ipv6 to my internal
network, and this works without problems.
But as soon as i have ipv6_gateway_enable="YES" in /etc/rc.conf rtadvd
doesn't set an ipv6 address on my vr0 interface. (Btw. the only interface
i have on the machine.)
Well, we don't know how to you configure your IPv6 router in manual. So
you'd better show us the information like your manual scripts if you
want to give more correct advices ;;
Ok to be totally clear:
# more /etc/rtadvd.conf
vr0:\
:addr="2001:16d8:ff50::":prefixlen#64:
Dosn't Work:
/etc/rc.conf: ipv6_gateway_enable="YES"
After boot i execute "rtadvd vr0" as root.
Works:
/etc/rc.conf: ipv6_gateway_enable="NO"
/etc/syscontrol: net.inet6.ip6.forwarding=1
After boot i execute "rtadvd vr0" as root.
The difference i belive is the setting of net.inet6.ip6.accept_rtadv=0 in
/etc/rc.d/network_ipv6 .
After digging around a bit i noticed that /etc/rc.d/network_ipv6 sets
net.inet6.ip6.accept_rtadv=0 and if i manually set
net.inet6.ip6.accept_rtadv=1 and then restart rtadvd things work and i get
an address on my interface.
Since i guess dissabling accept_rtadv is done for a reason i wonder what
is the correct way to setup ipv6 in /etc/rc.conf is?
Do you have native IPv6 addresses? If you do, i am proud of you. Anyway
you need to have a look IPv6 section of FreeBSD Handbook, rtadvd(8) and
rtadvd.conf(5). It will give you help. And you need to study IPv6 stuff
because it is not as easy as it seems, AFAIK. I mean you can solve your
matters if you study more.
Im trying as we speak, just wanted some input on how things are supposed
to work.
Im running /usr/ports/net/sixxs-aiccu to bring up the tunnel and my
adresses are assigned from them. www.sixxs.net for more information.
The tunnel works all the time (on the tun0 interface) so there isn't a
problem with my ipv6 connectivity. So i guess my question is: "Why is
net.inet6.ip6.accept_rtadv=0 in /etc/rc.d/network_ipv6 and how am i
supposed to configure ipv6 in /etc/rc.conf?"
PS: sixxs-aiccu is run from /usr/local/etc/rc.d/ so the reason things
doesn't work could be related to the fact that my tunnel goes live late in
the boot.
