Attached is a temporary solution for an already long standing problem with IPv6 and Network Manager. Without this patch the network connection is unstable because Network Manager waits for a DHCPv6 confirmation message which is blocked by the firewall. After the timeout of 45 seconds NM restarts the connection although it has been established already. When using wicked/ifup to establish the connection the system does not waits for the DHCPv6 message and the connection is stable. The patch also allows a mDNS message for the avahi-daemon, which gets blocked also. So IPv6 addresses get registered in avahi. -- fr.gr. member openSUSE Freek de Kruijf
