Windows 7 laptop with two active network connections will not perform DNS AAAA lookup under certain conditions

http://serverfault.com – My laptop has two network interfaces. The Ethernet interface connects directly to my provider's edge router. It obtains an IPv6 address via SLAAC. I manually set an IPv6 DNS server. The wireless interface connects to a CPE router that doesn't understand IPv6. If the wireless interface is disabled, I can reach the IPv6 Internet with no problems using the Ethernet interface. I run into problems when both interfaces are enabled and the wireless interface get its IPv4 DNS server via DHCP. Let's look at two scenarios. Wireless interface obtains IPv4 DNS server via DHCP - The CPE router (192.168 (HowTos)

How does Linux determine which network interface to use, when both are connected to the same network?

Note that this isn't a question on routing. I'm familiar with how that works.

Hi All,

I upgraded to CM 10.0.0 stable this morning and in the course of things noticed that IPv6 wasn't working on my WiFi connection. I have native dual stack available and all my other devices have connectivity for both ipv4 & ipv6 (on WiFi or Ethernet)

After a bit of digging I noticed that the wlan0 interface was getting a global ipv6 address but no default route was being added.

We recently set up a server on Debian Wheezy Beta 3 (x86_64) which has a native IPv6 connection.

We configured the eth0 interface to get the IPv6 configuration through some post-up hook commands in /etc/network/interfaces.

I use wicd to connect to wireless lans without probs and the relevant part of my rc.conf looks like this:# Use 'ifconfig -a' or 'ls /sys/class/net/' to see all available interfaces. # # Interfaces to start at boot-up (in this order) # Declare each interface then list in INTERFACES # - prefix an entry in INTERFACES with a !

After installing Debian stable (squeeze) I found that eth0 is not coming up, when I bring it up with "ifconfig eth0 up" only IPv6 is configured. Installation did happen in a home network with IPv6 enabled through a tunnel and a radvd router. Which makes me think it may have decided to disable IPv4, don't know how or why.

Hi, a week ago i switched from 11.1 to 11.2. Since then i can not really surf the web :/ its **** slow. First i thought it could refer to the router but no other system connected to the router is that slow. I read several threads facing these problems but disabling ipv6 and traditional network setup did not fix it. I even tried different kernels but always slow :(

AFAIK Ipv6 are unique over LAN and WAN

using this tutorial http://doc.pfsense.org/index.php/Using_IPv6_on_2.1_with_a_Tunnel_Broker

my lan network has now ipv4 connection and ipv6

I would like to be able to access my lan machines by their ipv6

i'm confused with firewall rules which i need to set to be able to do that

For now lets say that for the 3 interface (WAN / LAN / IPV6TUNNEL) i tell p

I've been trying to connect with ipv6 enabled networks with my Broadcom Wireless card under Ubuntu 12.04. The wireless card model is BCM4306.

Laptop gets the Internet through wifi. I'm trying to plug a router to the laptop to create a new wifi network. Laptop would bridge.
