So, it appears I missed the memo on the 4th of September from BT Exact, saying that the tunnel broker service will be down for a couple days. So, yea, no prolixium.com IPv6 connectivity for awhile, I guess.
In other news, I've spent a week on business in Charlotte, North Carolina so far. It's a pretty quiet town, and somewhat spread out. Seems filled with technology parks, a nice corporate atmosphere. I've gotten the chance to work with some high-end Netscreen hardware, and improve on my network troubleshooting skills.
Speaking of Netscreen hardware, I've been working lately on setting up a VPN tunnel between Linux 2.6 (using Racoon, and the KAME project) and Netscreen's ScreenOS. It seems that the NAT-T (NAT traversal) feature of Racoon is either broken, or I completely misconfigured it. The latter, most likely. Once I get it working smoothly, I'll post a howto, since there seems to be a lack of complete documents on how to setup such tunnels.
