QOS_FILTER_x_PORT Ports and port ranges can be set here, separated by spaces and

combined in any manner. If this variable is empty traﬃc on all ports will be limited.

Filtering for a port range from 5000 up to 5099 would look like this:

QOS_FILTER_x_PORT=’5000-5099’

Another example: If traﬃc on ports 20 to 21, 137 to 139 and port 80 should be ﬁltered

to the same class this would look like this:

QOS_FILTER_x_PORT='20-21 137-139 80'

This variable can be empty.

Important:

• If ﬁltering for ports QOS_FILTER_x_PORT_TYPE has to be set as well.

• Port ranges will be ignored if ﬁltering for ACK, TOSMD, TOSMT, TOSMR or

TOSMC takes place by the use of QOS_FILTER_x_OPTION.

QOS_FILTER_x_PORT_TYPE This variable is only valid and important in conjunction

with QOS_FILTER_x_PORT (it is ignored in other cases).

Ports in client mode are diﬀerent from those in server mode. Specify here if a port is of

type server or client. Use PCs from your own net as a point of reference to decide what

to use. Possible settings:

QOS_FILTER_x_PORT_TYPE='client'

QOS_FILTER_x_PORT_TYPE='server'

As of version 2.1 a combination of those two arguments is also valid to put traﬃc from

the own net as well as traﬃc from the Internet into the same class on this port.

QOS_FILTER_x_PORT_TYPE='client server'

This equals to two similar ﬁlters once with QOS_FILTER_x_PORT_TYPE set to client and once

set to server.

QOS_FILTER_x_OPTION This variable activates additional properties for the ﬁlter. Only

one of the following arguments can be passed (a combination wouldn’t make sense in

the same ﬁlter). It is perfectly right and makes sense sometimes to set a ﬁlter for ACK

packets and a second ﬁlter for TOSMD packets to move their packets to the same target

class (see QOS_FILTER_x_CLASS).

ACK Acknowledgement packets.

A packet matching this option is sent as an acknowledgement to a data packet. If
