This form defines TOS (Type Of Service) rules, which add a TOS value to matching packet headers.
Whenever a packet passing through the firewall matches the criterion defined here, it will be added the corresponding TOS value.
| Rule ID | The unique ID number identifying this TOS rule. |
| TOS | Choose the type of treatment that will best suite the kind of packets matched by this rule. |
| Client | The zone from which the packet is originated. The matching can be narrowed by specifying: a precise IP, interface or subnet in the middle field; or even a port number in the right field. Leave "-" in a field for matching any IP or port. |
| Server | the zone to which the packet is directed. The matching can be narrowed by specifying a precise IP, interface or subnet in the middle field; or even a port number in the right field. Leave "-" in a field for matching any IP or port. |
| Protocol | The protocol type associated to that service. |
Example: you want FTP data packets to be handled so that the rate transfer is maximized, disregarding reliability and delay, in all directions.
| TOS | Maximize-Throughput (8) |
| Client | all |
| Server | all |
| Protocol | ftp-data |
