I'm having some problems while testing a simple IPv6 network. I need to implement IPv6 at my work, but before i'm learning it and testing it too. This is the most basic test i could do and i'm still having problems. I have two work stations: one Windows 7 Ultimate and another a Linux - Slackware 13.1 32 bits. Thats like this. The W7 is configured with the following address 2001::2/64 and the Linux with 2002::2/64. I ping from W7 until 2000::2/16 but i can't ping to 2002::1. When i make the same testing with two Linux systems it's okay but W7 it's not. Can anyone help me? Thanks, Pedro Diniz

Hi, According the issue, I suggest that you may try to capture network package to confirm the status of ICMP package. You may capture network package by following steps: 1) Download NetMon3.4 from the following website and install it on the computer http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=983b941d-06cb-4658-b7f6-3088333d062f 2) Launch NetMon3.4. 3) In the Microsoft Network Monitor 3.4 window, click Create a new capture tab … 4) In the new tab, select all the Network Adapters in the Select Networks window. 5) Then, switch to Network Monitor, press F5 to start NetMon. 6) Try to repro the issue. 7) Go back to the NetMon window and press F7 to stop the NetMon. 8) Press Ctrl+S to save the Netmon file named test. 9) Upload the file via SkyDrive ,and post a link here. If you cannot receive the Echo reply package, you may check the setting of your routers. Also capture network package from the route 1, check whether it receive an Echo request package.
