Im using Ubuntu
Im using a dlink 615 router also
what changes do i have to make for the config script to work that HE tunnel supplies?
You may not need the script. IPv6 autconfiguration seems to work with Linux and the DLINK 615 (Revision C1) without any script for me.
You should make sure that your tunnel is terminated on one or the other, ideally the dir-615 if it is upstream of the ubuntu machine. Then use the routed /64 in the dir-615 with either dhcp or ra and let the machines configured themselves.
