Need help on two iptables related commands
 
I have the following two commands dealing with iptables that I don't fully understand. Can someone help me a bit?

iptables -A INPUT -i lo -j ACCEPT
iptables -A OUTPUT -o lo -j ACCEPT

Thanks!

That iptable rule is saying to accept any incoming or outgoing connections on the loopback interface. Loopback is the 127.0.0.1 which routes back to your computer/server.
