Thanks very much, rpnc! :)
I also have 10.03.1 (r29592). Are you using bcrm-2.4 or brcm47xx? For some reason I am unable to add traceroute6:
root@DeltaNet:/etc# opkg update
Downloading »downloads.openwrt.org/backfire/1 ··· kages.gz.
Inflating »downloads.openwrt.org/backfire/1 ··· kages.gz.
Updated list of available packages in /var/opkg-lists/packages.
root@DeltaNet:/etc# opkg install iputils-traceroute6
Unknown package 'iputils-traceroute6'.
* opkg_install_cmd: Cannot install package iputils-traceroute6.
Thanks very kindly for your detailed post, I will go through it and see if I can figure out where I went wrong.
