Maximum Bandwidth
The maximum bandwidth instructs the security policy what the largest amount of traffic allowed using the policy. Depending on the service or the users included for the security policy, this number can provide a larger or smaller throughput depending on the priority you set for the shaper.
Setting Maximum Bandwidth to 0 (zero) provides unlimited bandwidth.
Maximum Concurrent Connections
Enter the maximum allowed concurrent connection.
Forward DSCP
Reverse DSCP
Enter the number for the DSCP value. You can use the FortiGate Differentiated Services feature to change the DSCP (Differentiated Services Code Point) value for all packets accepted by a policy. The network can use these DSCP values to classify, mark, shape, and police traffic, and to perform intelligent queuing. DSCP features are applied to traffic by configuring the routers on your network to apply different service levels to packets depending on the DSCP value of the packet.
