Nothing to worry about, this is actually on the site. However the output is collapsed by default because it's very long. CTRL+F "View the original iptables rules" and click it, you will see what you saw in the source.
THANKS! I was literally about to format my entire computer and hard-reset my router. I freaked out badly. I really shouldn't be snorting DMT all day like this while browsing. You saved me.
