Not receiving temp IPv6 address from router

ahronzombi · 2012-02-11 21:47:42

I have spent the day trying to get IPv6 internet connectivity working in Arch and Im failing. No matter what I do my Arch install just isnt receiving and ipv6 temp address. If I use the exact same system but boot into another OS i automatically get an IPv6 temp address and can ping 1pv6.google.com .

If there is anything that might prevent this networking function from working Id appreciate to know what it could be. Thanks a lot.

Are you using WICD or Network Manager or ifup?

I use net profiles and have a profile for my bridge.

INTERFACE="br0"
CONNECTION="bridge"
DESCRIPTION="Gigabit Bridge"
PRE_UP="ip link set dev eth0 promisc on"
BRIDGE_INTERFACES="eth0"
IP="static"
IP6="stateless"
ADDR='192.168.11.66'
GATEWAY='192.168.11.1'
DNS=('8.8.8.8')

Just to give it a shot I reconfigured my networking to go via network-manager and that didnt help. So i went back to netcfg

I just cleared my iptables, that didnt seem to help either

I wont consider this solved until auto config works but in the mean time I have an ugly work around. I created a profile for eth0 to come up at 0.0.0.0 and I got static ipv6 working in my bridge like this

INTERFACE="br0"
CONNECTION="bridge"
DESCRIPTION="Gigabit Bridge"
POST_UP="ip -6 route add default via fe80::c851:85ff:fed0:e71f dev br0"
BRIDGE_INTERFACES="eth0"
IP="dhcp"
IP6="static"
ADDR6=(2001:470:1f07:be8:bd9a:b66d:248a:b866/64)
Gateway6=fe80::c851:85ff:fed0:e71f
ADDR='192.168.11.66'
#ROUTES=('192.168.0.0/24 via 192.168.1.2')
#GATEWAY='192.168.11.1'
#DNS=('8.8.8.8')

What's the reason for using a bridge?, never seen ipv6 autoconf play well with bridges in the past.

I use a bridge to allow my KVM virtual servers to connect to the network. I know the bridge isn't the issue, its got to be arch. I have tried it directly with eth0 and have the same problem, also all of my VMs that run off that bridge receive ipv6 autoconf.

no an easy one to solve is it? I bet its some kind of kernel setting but i feel like ive looked at them all, can t hey be set to defaults?

I had the same problem and was also stumped until I remembered that activating forwarding (e.g. net/ipv6/conf/all/forwarding) disables the stateless attribution of IPv6, as well as the temporary addresses. Since this forwarding mode is (only?) used by routers, bridged interface should not need it.

Are you sure the other OS you're testing is not getting assigned a tunneled (Windows does this) or stateless address?
