Thank you very much for this great firmware modification. I was searching around a little bit if anyone already had added support for aiccu, which is a special IPv6 tunnelling software provided from Sixxs: http://www.sixxs.net/archive/sixxs/aiccu/unix/aiccu_current.tar.gz I already managed to have aiccu integrated in your most recent source tree; it compiles and works just fine , the only thing I did not manage to find out is how to add a new menu entry for Aiccu in the IPv6 tab and to generate the configuration file based on the given input. The configuration info is pretty simple: username string password string tunnelid string use TLS boolean AICCU needs to be started after the timebase via NTP has been received. I searched in the source tree and found out that Asus does the complete startup handling in C code. Is there an easier way to start the daemon dependant on the availability of a valid system time?
