Sorry I might not have been overly clear... I've installed everything from the pre-req's with the exception of iptables. I have access to Extras-Devel (set it up from day one) and have Kernel Power installed from a previous attempt to tether using MobileHotspot unfortunately iptables package isn't showing up in the list of apps for me so I'm unable to install it. Appreciate the quick response 9000, thanks
