I have a problem with my ipv6 connection and have now narrowed it down to something I can reproduce and analyze - just don't have the skill needed to figure it out. I have native adsl ipv6 from teksavvy that goes to a linux firewall. This serves me ok and I can reach a lot of ipv6 stuff but some fails. From internal server to http://ipv6.google.com - fine From firewall to http://meinenigma.com - fine From internal server to http://meinenigma.com - problem, only get the first few bytes. Did a tcpdump and it looks to me like the other side stops sending data and after 3 seconds my side sends [ACK,FIN]. If the other side truly stops sending data why does it work when done directly on the firewall (=no routing) ? If MTU - why does it work on firewall? If it's MTU or a routing issue why does google work ? I did lower MTU on ppp1 (the ipv6 connection) to 1412 but still same issue. Does anyone have any suggestions on what to look for ? -- ------------------------------------------------------------------- Techwiz, Peter Sjoberg GPG key (42DDDDDD) on keyserver & homepage Key fingerprint = EB81 3135 1636 576A DA83 826B 2455 0E88 42DD DDDD Homepage: http://www.techwiz.ca/~peters Pictures: http://www.flickr.com/photos/henahadu/
