QOS_FILTER_x_CLASS='25'
By QOS_CLASS_x_DIRECTION it is set if a class belongs to up- or downstream. If a filter
is set then queueing packets to an upstream class only upstream packets will be filtered
and queued to the class mentioned. QOS_CLASS_x_DIRECTION defines the “direction ” of
filtering.
As of version 2.1 more than one target class can be set. If for example traffic on port
456 upstream and downstream is our target
QOS_FILTER_x_CLASS='4 25'
would be specified, if class 4 is the upstream class and 25 is the downstream one. It does
not make sense to specifiy more than one up- or downstream class so there never will be
more than two target classes.
QOS_FILTER_x_IP_INTERN Set IP addresses and IP ranges from internal networks here
which should be filtered. They have to be separated by spaces and can be combined in
any manner.
An example:
QOS_FILTER_x_IP_INTERN='192.168.6.0/24 192.168.5.7 192.168.5.12'
This filters all IP addresses that match 192.168.6.X and in addition IP 192.168.5.7 and
192.168.5.12.
This variable can be empty.
If this variable is used in conjunction with QOS_FILTER_x_IP_EXTERN only traffic between
IPs or IP ranges defined by QOS_FILTER_x_IP_INTERN and QOS_FILTER_x_IP_EXTERN will be
filtered.
Important: If filtering by QOS_FILTER_x_OPTION for ACK, TOSMD, TOSMT, TOSMR
or TOSMC takes place and variable QOS_CLASS_x_DIRECTION is of target class ’down’ this
variable will be ignored.
QOS_FILTER_x_IP_EXTERN Specify IP addresses and IP ranges from external networks
(being connected on QOS_INTERNET_DEV) here which should be filtered. They have to be
separated by spaces and can be combined in any manner. This works the same way as
QOS_FILTER_x_IP_INTERN.
This variable can be empty.
Important: If filtering by QOS_FILTER_x_OPTION for ACK, TOSMD, TOSMT, TOSMR
or TOSMC takes place and variable QOS_CLASS_x_DIRECTION is of target class ’down’ this
variable will be ignored.
