I used to have a static tunnel on OpenWRT Attitude Adjustment (12.09) with 6tunnel and static configuration (without AICCU, without DHCP6). It worked well. Now, I changed routers and installed the new OpenWRT which comes with native support for 6in4 tunnels. I cannot however get it to run reliably. First, I configured it for AICCU, config interface 'wan6' option proto 'aiccu' option username 'my-handle/tunnelid' option password 'my-password' option requiretls '1' It works when network is reloaded manually /etc/init.d/network reload, and the router itself at least has IPv6 connectivity, but usually doesn't come up on boot. Logs return errors like Thu Nov 27 15:02:42 2014 local7.err syslog: Couldn't resolve host tic.sixxs.net, service 3874 Thu Nov 27 15:02:42 2014 local7.err syslog: Couldn't connect to the TIC server tic.sixxs.net Thu Nov 27 15:02:42 2014 local7.err syslog: Couldn't retrieve first tunnel for the above reason, aborting which seems to indicate that AICCU starts too soon, before the IPv4 network is up. It also doesn't announce the prefix in my network but that's probably a downstream issue. Second, I tried a static configuration analogous to my previous 6tunnel configuration, and as recommended by OpenWRT documentation config interface 'wan6' option proto '6in4' option mtu '1424' option peeraddr 'pop's.ipv4.ip' option ip6addr 'my:ipv6:tunnel:endpoint' option ip6prefix 'my:prefix/48' This works fine locally (stateless configuration on clients) but doesn't actually connect me to the tunnel. There is no outside IPv6 connectivity. What is the recommended configuration for Barrier Breaker? Is there a way to get AICCU to start at the right time? Or should I configure the tunnel manually? And if so, how?
