I am new to iptables.
I want to open all ports of vcsa (everything ) for few servers. And close any traffic from any other server (only for incoming traffic )
is there any problem with these rules.
iptables -A INPUT -s 192.168.1.12/24 -p all -j ACCEPT # this will open everything from .12
iptables -A INPUT -s 192.168.1.13/24 -p all -j ACCEPT
<few more servers......>
iptables -A INPUT -j DROP # drop everything
any suggestion.
