iptables

[laci]

What is the difference between

iptables -A INPUT -j DROP and
iptables -A INPUT-s 0.0.0.0/0 -j DROP?

Will this deny any request for those who use this server as a gateway;

if i use:

iptables -A INPUT -s ip_address -j ACCEPT

will i guarantee access to ip_address inside the server?

Dear laci,
Hello,

iptables -A INPUT -j DROP and
iptables -A INPUT-s 0.0.0.0/0 -j DROP?

Nothing both rule doing same thing

iptables -A INPUT -s ip_address -j ACCEPT

Yes
