Hello, I set up with AICCU (Version: 2006.07.23-gui-win32 tunnel T24636 to usqas01. Set the workstation to be "DMZ host" on my Linksys router. Tunnel does not seem to work, I am at a loss on how to proceed. I can ping -6 my locally assigned interface 2001:4830:.....::2, but cannot seem to reach the pop-end 2001:4830:.....::1. Tried with XPsp2 and VistaHome, same results. ipconfig shows aiccu tunnel is getting set up in XPsp2 system, but Vista does not show the aiccu tunnel at all (??) even though the GUI reports all the "right" information. It seems if I wait long enough (120 seconds? 600 seconds?) even the XPsp2 drops the aiccu tunnel setting(s). I can ping to 66.117.47.228 (pop ipv4 addr). I can traceroute to iad0-sixxs.hotnic.net [66.117.47.228] Tracing route to iad0-sixxs.hotnic.net [66.117.47.228] over a maximum of 30 hops: 1 * * * Request timed out. 2 * * * Request timed out. 3 * * * Request timed out. <snip repeats> 13 * * * Request timed out. 14 23 ms 23 ms 22 ms iad0-sixxs.hotnic.net [66.117.47.228] Trace complete. Will try from another location (coffee shop) tomorrow. If aiccu does not work what are my options? Switching tunnel type to AIYIA requires more credits than I have at the moment, not sure how to get more unless the tunnel is actually up. Perhaps I can offer a clarification to the documentation to earn some credits: On the "Request tunnel" page, it mentions that the tunnel drops if no response is received in 120sec, but the heartbeat info page (FAQ?) indicates the tunnel drops if no heartbeat is received in 600sec, and the 120sec is the allowable timestamp offset (with reminder to use NTP to avoid getting too far off the right time). It seems the correction should be made to the tunnel request page to clarify that tunnels drop after 600sec without a response. Unfortunately my "request tunnel" option is disabled (insufficient credits) so I cannot confirm my recollection. Any suggestions would be welcome - thanks !
