This is part of the Android Clat project.

Installation instructions

• This requires a phone that supports IPv6 over the cellphone network. The current (2012) list of phones that support this are: Nexus S, Galaxy Nexus, Galaxy S2, Galaxy S3, Galaxy Note 2, and all Verizon LTE phones
• This also requires a cellphone network that supports IPv6. Current (2012) list of networks: T-Mobile, Verizon
• You will need to root your phone if you haven't already. Instructions on how to do that are found elsewhere on the internet.
• Install this APK: FourSixFourXlat.apk
• The first time you run it, grant it root permissions
• When you're on an IPv6-only mobile connection, 464xlat/clat will start
• When you turn on your phone's built-in tethering (Under Settings > Wireless & Networks - More > Tethering & portable hotspot), your /64 will be configured on the tethered interface

How do I switch the cell internet connection to IPv6 (for t-mobile)?

Go to Settings > (Wireless & Networks) More > Mobile Networks > Access Point Names > and add: name="T-Mobile US IPv6", apn="epc.tmobile.com", type="default", protocol="IPv6"

How can I test that 464xlat is operating properly?

While on the IPv6 APN, visit this helpful ipv6 test page

Where can I see the source code?

The source code is on github

I have a question that isn't covered by the FAQ
