What, you may ask, does Windows Mobile 6.1 have to do with a Sixxs IPv6 tunnel? Well, AT&T/Samsung just released the upgrade from WM6.0 -> WM6.1 for my BlackJack II (SGH-i617), and in so-doing, have permitted the use of the "Internet Sharing" application. I'd already unlocked this functionality under WM6.0, so I was expecting no problems moving forward... I was wrong. Upon bringing up the bluetooth PAN connection between my phone and my laptop (Ubuntu Linux), I was somewhat pleased to find that the interface was now given an IPv6 address -- it never was before: Unfortunately, the IPv6 address that I was given is not routed .. and the routes that were given by default interfered with the ability of aiccu to bring up my Sixxs tunnel. It turns out that now, instead of using "Media Net" to do the interconnect (with no IPv6), WM6.1 uses "AT&T ISP" (with unrouted IPv6) .. I could really care less, but it broke my tunnel and that's just not acceptable. Here's the work-around that I came up with: In the /etc/network/interfaces file, for the "bnep0" interface (bluetooth PAN), I added this: This works, but if anyone knows of a "cleaner" way to do this, please let me know.
