It seems that dedus01 is not working at the moment. I tried with Windows 7 (freshly downloaded aiccu.exe) and Ubuntu 10.10 (provided aiccu). On both systems I cannot ping the POP inner tunnel endpoint (aiccu test 6/8). Following is the output from "aiccu test": Tunnel Information for T46805: POP Id : dedus01 IPv6 Local : 2a01:198:200:a41::2/64 IPv6 Remote : 2a01:198:200:a41::1/64 Tunnel Type : ayiya Adminstate : enabled Userstate : enabled ####### ####### AICCU Quick Connectivity Test ####### ####### [1/8] Ping the IPv4 Local/Your Outer Endpoint (192.168.178.29) ### This should return so called 'echo replies' ### If it doesn't then check your firewall settings ### Your local endpoint should always be pingable ### It could also indicate problems with your IPv4 stack PING 192.168.178.29 (192.168.178.29) 56(84) bytes of data. 64 bytes from 192.168.178.29: icmp_req=1 ttl=64 time=0.017 ms 64 bytes from 192.168.178.29: icmp_req=2 ttl=64 time=0.013 ms 64 bytes from 192.168.178.29: icmp_req=3 ttl=64 time=0.014 ms --- 192.168.178.29 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2000ms rtt min/avg/max/mdev = 0.013/0.014/0.017/0.004 ms ###### Did this work?

[Y/n] n I read a few other tickets about similar problems and I suspect that this is another "hiccup" in the POP software. Thanks in advance for any help, Joachim Breitsprecher
