Hi,
I want to configure firewall such that network 192.168.1.0/24 can
only access http server from server1(192.168.0.2/24) and
network
192.168.0.0/24 can not access http server. So I tried this:
#service iptables stop
#iptables -P INPUT DROP
#iptables -t filter -A INPUT -s 192.168.1.0/24 --dport 80 -j ACCEPT
But this command sends error that "Unknown arg: --dport"
HOW CAN I ACHIEVE THIS?
ALSO IS THERE ANY BOOKS OR ONLINE DOCUMENTS FOR PRACTICALLY LEARNING OF IPTABLES?
TnR
