It seems the AICCU tunnel I have configured on my Windows XP workstation is not working. I have obtained 5 points credit for having the tunnel up for a week. Hence, I know the tunnel is "up". I have been digging through the forums for assistance and seeking out as much documentation as I can in an effort to make the tunnel work. An attempt to reach any IPv6 address results in something like the following: Pinging 6bone.net [2001:5c0:0:2::24] from fe80::20c:6eff:febf:9221%5 with 32 bytes of data: Reply from fe80::20c:6eff:febf:9221%5: Destination address unreachable. Reply from fe80::20c:6eff:febf:9221%5: Destination address unreachable. Reply from fe80::20c:6eff:febf:9221%5: Destination address unreachable. Ping statistics for 2001:5c0:0:2::24: Packets: Sent = 3, Received = 0, Lost = 3 (100% loss), I do not see the IP address that I was assigned (shown in the tunnel information window) does not show up on any interface. I assume this is the issue. Below is the result of an "ipconfig /all": C:\Documents and Settings\grossia>ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : zmodem1 Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Unknown IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : 3Com Gigabit LOM (3C940) Physical Address. . . . . . . . . : 00-0C-6E-BF-92-21 Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 10.0.0.90 Subnet Mask . . . . . . . . . . . : 255.255.255.0 IP Address. . . . . . . . . . . . : fe80::20c:6eff:febf:9221%5 Default Gateway . . . . . . . . . : 10.0.0.254 DNS Servers . . . . . . . . . . . : 10.0.0.92 fec0:0:0:ffff::1%1 fec0:0:0:ffff::2%1 fec0:0:0:ffff::3%1 Tunnel adapter Teredo Tunneling Pseudo-Interface: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Teredo Tunneling Pseudo-Interface Physical Address. . . . . . . . . : FF-FF-FF-FF-FF-FF-FF-FF Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : fe80::ffff:ffff:fffd%4 Default Gateway . . . . . . . . . : NetBIOS over Tcpip. . . . . . . . : Disabled Tunnel adapter Automatic Tunneling Pseudo-Interface: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Automatic Tunneling Pseudo-Interface Physical Address. . . . . . . . . : 0A-00-00-5A Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : fe80::5efe:10.0.0.90%2 Default Gateway . . . . . . . . . : DNS Servers . . . . . . . . . . . : fec0:0:0:ffff::1%1 fec0:0:0:ffff::2%1 fec0:0:0:ffff::3%1 NetBIOS over Tcpip. . . . . . . . : Disabled Tunnel adapter Automatic Tunneling Pseudo-Interface: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Automatic Tunneling Pseudo-Interface Physical Address. . . . . . . . . : C0-A8-01-02 Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : fe80::5efe:192.168.1.2%2 Default Gateway . . . . . . . . . : DNS Servers . . . . . . . . . . . : fec0:0:0:ffff::1%1 fec0:0:0:ffff::2%1 fec0:0:0:ffff::3%1 NetBIOS over Tcpip. . . . . . . . : Disabled Any tips would be appreciated. -Anthony Tunnel ID T10380 Tunnel Type ayiya
