10-36 Administrator’s Handbook
In previous software versions, a filter would either
pass
or
block
the specified traffic. Motorola Netopia®
Embedded Software Version 8.7.4 adds a third option,
force routing
. You specify a gateway IP address, and
each packet matching the filter is routed according to that gateway address, rather than by means of the global
routing table.
In addition, the TOS field has been added to the classifier list in a filter. This allows you to filter on TOS field
settings in the IP packet, if you desire.
The new filterset screen appears as follows:
To use the policy-based routing feature, you create a filter that for wards the traffic.
•
Toggle
Forward
to
Yes
. This will display the Force Routing options.
•
The
Call Placement/Idle Reset
setting is used to determine if a packet which matches the filter will cause
an “instant-on” link to connect, if it is down; or reset its idle timer, if it is already up.
If you select
No Change
from the
Call Placement/Idle Reset
pull-down-menu, a match on this rule will
keep the WAN connection alive by resetting the idle-timeout status.
If you select
Disabled
, a match on this rule will not reset the idle-timeout status.
For example, if you wanted ping traffic
not
to keep the link up, you would create a filter which for wards a
ping, but with the Call Placement/Idle Reset set to Disabled.
•
Toggle
Force Routing
to
Yes
.
•
Enter the
Gateway IP Address
in standard dotted-quad notation to which the traffic should be for warded.
•
You can enter
Source
and
Destination IP Address
(es) and
Mask
(s),
Protocol Type
, and
Source
and
Destination Port ID
(s) for the filter, if desired.
