I am trying to use my shiny new IPv6 tunnel, but I'm getting a bit lost. After folowing some howtos, trying things manually (which didn't work out), I decided to give aiccu a try. I'm ending with the same result. At this point I'm only trying to make my workstation IPv6 compatible. This PC is behind a NAT router which supports IPv6-in-IPv4. In the past few days I did try some other tunnel brokers and they did work. So it is possible. I'll explain my steps and hopefully, someone knows what's the problem. The steps I took: 1) emerge aiccu -- Worked very well 2) Created /etc/aiccu.conf List of the options in the configuration file: username ML51-6BONE password ******* ipv4_interface eth0 ipv6_interface sixxs verbose true daemonize true automatic true 3) /etc/init.d/aiccu start Looking at syslog, everything went fine, but I still don't have an proper IPv6 tunnel, I cannot ping6 the end of the tunnel. * Starting aiccu ...
