Hello,

I apologize if I have the wrong forum here. I'm running openSUSE 13.2 (Harlequin) (x86_64) 64-bit and I'm worried that maybe someone has gotten into my system. Here's the output from iptables -L
Code:

The first line worries me. I don't know a lot about iptables but isn't that allowing any connection from anywhere into my system? Doesn't it essentially nullify the rest of my firewall because it's the first rule in the list? Any help would be greatly appreciated. Thank you.
