I need to do few port forwardings with my Mango GT, if I run the command directly, it works and the rule appears in the inptables list. However, when I put them in rc.local file to be executed in boot-up, it doesn't work! Looks like the iptables is overwritten by something else during booting up.
I don't have this problem with normal Raspbian, it works there. Any thoughts??
Thanks to @CraigWeb, it's solved:
"What I was trying to say is that this is a rasbian issue and that I have found multiple threads where people have failed when putting rules in rc.local.
