Configure security settings
Using [inspect-state] with the stat option
You can use the inspect-state with the stat option. The stat option causes this firewall rule to
record statistics associated with this firewall rule. Transaction times, counts and errors are
recorded under the PPP statistics with this option.
Assigning DSCP values
When using QOS, packet priorities will be determined by the DSCP values in their TOS fields. These
priorities may have already been assigned but if necessary, the router can be configured to assign
them by inserting the appropriate rules in the firewall. This is done by using the dscp command.
For example, the following rule sets the DSCP value to 46 for almost any type of packet received on
ETH 0 from IP address 100.100.100.25 addressed to 1.2.3.4 on port 4000. This allows you to set the
DSCP value for almost any type of packet.
dscp 46 in on eth 0 from 100.100.100.25 to 1.2.3.4 port=4000
As a further example, the following rule causes outgoing mail traffic to the same top priority queue
(46 is, by default, a very high priority code in the DSCP mappings):
dscp 46 in on eth 0 proto smtp from any to any
