Use AirPort Utility to set up and manage your 802.11n and 802.11ac AirPort base stations, including AirPort Express, AirPort Extreme, and AirPort Time Capsule. AirPort Utility 6.3.1 resolves an. In the airport choice behavior literature, the first concern is choice dimension. One approach is to consider airport choice as single dimensional but with specific attributes of different choice dimensions (Basar and Bhat, 2004, Hess and Polak, 2005, Zhang and Xie, 2005, Hess, 2010). Another is the multidimensional approach, combining airport.
Below are two methods for configuring the Airport Aiport to connect to use IPv6. Note that only the Airports supporting 802.11N have support for IPv6.
Automatic Tunnel
The simplest approach to getting IPv6 connectivity with the Apple Airport is simply to use the automatic setting. To do this open 'Advanced -> IPv6' and then set IPv6 mode to 'tunnel' and configure IPv6 to 'automatically'.
Optionally check 'block incoming Ipv6 connections' and then configure the exceptions in the IPv6 Firewall tab.
SixXS Tunnel
The instructions in this section are based on a forum posting, and document how to configure the Apple Airport so that it can connect to Sixxs and have a pingable IPv6 tunnel established. The local LAN gets RA. LAN clients get IPv6 connectivity.
The first thing to do is ensure that the Sixxs.net tunnel setting (via your home page) is set to '6in4-static', since this is the only option supported by the Airport at this time. This will require you having a static IPv4 address.
Airport Utility 6.3.1 For Mac
This is was last tested with AirPort firmware 7.6.3 and AirPort Utility 6.3.1.
- Edit your base station settings and select the Internet tab.
- Click Internet Options… button
- Enter these
- Configure IPv6: Manually
- IPv6 Mode: Tunnel
- IPv6 WAN Address: Your IPv6
- IPv6 Default Route: PoP IPv6
- Remote IPv4 Address: PoP IPv4
- IPv6 Delegated Prefix: Your subnet's Subnet Prefix as xxxx:xxx:xxxx:xxxx::/64
- IPv6 LAN Address: An address in the Subnet Prefix that you want the base station to have. Something like xxxx:xxx:xxxx:xxxx::1
With some older Airport firmware >= 7.5.0 you have to 'fix' your IPv4 address. With your Internet connection configured with IPv4 on DHCP, you will be able to enter all information for IPv6 as listed, but nothing will work. (On 7.6.3 that is no longer the case) |
Note: Older versions of the Apple Airport Software (prior to 7.4.2) had different nomenclature for configuration under the Advanced > IPv6 tab. |
Then, in the IPv6 Firewall section, I added an entry:
The only drawback appears to be is that the firewall entry for the tunnel public interface is limited to either 'Allow Specific TCP and UDP ports' or 'All services and ports' -- so to open up ICMP, you have to allow all TCP and UDP as well.
Note: There appears to be a bug in 7.4.2 of the Airport firmware that prevents it from working properly in IPv6 mode, unless it is using Ethernet/manual for the connection to the WAN, so it would appear you are out of luck if you are using PPPoE. -- is this still the case in the later firmware, or 7.4.2 if the tunnel is correctly set at Sixxs? |
Note: Newer versions of the Apple Airport Software (7.4.2 and later) have new nomenclature for configuration under the Advanced > IPv6 tab. The new configuration settings, with mappings to the SIXXS tunnel approval email details: |
I do not have a subnet as of yet, as I'm new to SIXXS as of the change, but will update the 'LAN IPv6 Address' once I have an assigned subnet and have fully tested, which will take several weeks while I reup my ISK credits. I assume it won't change from the previous version.
Apple Airport 7.5.2 Software
Airport Utility 5.6
With Apple Airport version 7.5.2 the tunnel does not come up unless there is a LAN subnet assigned. As I did not initially have a subnet available I manually configured a fake subnet which allowed the tunnel to come up. Using the Automatic IPv6 Tunnel Configuration option did not succeed at all.
It is also not required to configure the IPv4 address statically but they could be left on DHCP. Daemon tools for mac os x 10.8.
