Hello!

I started to build a little iptables/firewall script.

but when i run it i get that error:

iptables: No chain/target/match by that name

I found helpon the web, but they just say that i need to load a module.

Well, why doesn´t it say which module it needs?

### Flush Tables
iptables -F FORWARD
iptables -F INPUT
iptables -F OUTPUT

### default policies
iptables -P FORWARD DROP
iptables -P OUTPUT ACCEPT
iptables -P INPUT DROP

### the local loopback interface (-i lo) is open to all the various types
### of IP packets (-p all).
iptables -A INPUT -i lo -p all -j ACCEPT

### Ping
iptables -A INPUT -p icmp -j DROP

### Block all Incomming Packets with SYN Flag
iptables -A INPUT -p tcp ! --syn -j ACCEPT

### Allow serices
iptables -A INPUT -p tcp --dport 22 -j ACCEPT

### Block ANY connections from gateway
iptables -A INPUTn -s 192.168.10.3 -j DROP

Thank you!
