Figure 25: IP Tables Append Rule (table: filter, chain: INPUT)

Note: For many parameters, there is a checkbox called inverted. Checking this

box will invert the sense of the parameter.

Target Indicates the action to be performed when the IP packet

matches the rule. The kernel can ACCEPT the packet, DROP it,

LOG it, REJECT it by sending a message, translating the source or

the destination IP address/port (in the nat table) or send the

packet to another user-defined chain. All the options are in the

target list.

Source/Destination IP Indicates how the source/destination IP address should be.

When a network should be included in the rule, the network

mask must be configured too.

Input/Output

interface

Indicates the interface where the IP packet should pass. The

Input Interface option will appear only for the chains INPUT,

FORWARD and PREROUTING; the Output interface option will

appear for the chains FORWARD, OUTPUT and POSTROUTING.
