4.2.6. Managing persistent tables and rules
This example creates a new table with table id 1 and then adds a rule to drop all ICMP packets
for port 0. The rules in a table are not active until the table is activated.
Create a table:
[root@host]# redirect ethX create_table --table 1
Activate the table:
[root@host]# redirect ethX activate_table --table 1
Add a rule to the newly created table:
[root@host]# redirect ethX add --table 1 --proto icmp –-action drop –-port 0
The redirect dump command can be used to save the currently configured tables and rules
into a shell script.
