IP Tables - Need understanding on a rule

Question

iptables -A FORWARD -s 0/0 -i eth0 -d 192.168.1.58 -o eth1 -p TCP \ --sport 1024:65535 --dport 80 -j ACCEPT

Answer 1

This rule is applied to packets that are traversing the firewall. It ACCEPTs (allows) packets that match the following properties:

• incoming interface is eth0
• outgoing interface is eth1
• any source IP
• destination IP is 192.168.1.58
• protocol is TCP
• source port is between 1024 and 65535
• destination port is 80 (HTTP)

In the future, questions such as this are better suited towards SuperUser or ServerFault rather than StackOverflow.
