Editing TOS Rules

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.
