Let's say I have an internal address of 192.168.0.2 and an external address of 1.222.333.4
My external IP should, by default, be mapped to my internal IP.
But how should I allow connections into my external IP with an iptables rule?
I have no interface set up for the outfacing network, should I create a DHCP outfacing network card (How would I go about doing this, if this is the case?) or should I do it another way? - Maybe with a FORWARD rule? I am not sure. I imagine it would be easier to make an outfacing network card.
