First: The question has been moved to superuser. In my opinion it should have been moved to serverfault. What can I do?

Second: I try to answer questions on iptables/netfilter. I end up answering questions on unix.stackexchange.com, serverfault.com, stackoverflow.com and now even superuser.com. It is very cumbersome since I've just started and I am missing reputation to do simple tasks.

What site do these questions really belong to and can I have them moved to that site?

Of course sometimes I answer with a netfilter-solution where it wasn't clear that this can be a solution. These question can stay where they are and so they can be answered using other solutions.
