How to Run FILTCFG
Setting Up
You use the Filter Configuration utility (FILTCFG) to configure filters that
selectively control which packets will be sent or received by a router. Filters
let you control the service and route information that is accepted or advertised
by a router.
Filters can be useful when you want to limit specific kinds of traffic to certain
parts of your network topology, or when you want to provide a certain level
of security.
Before you begin, make sure that the Filter Support option is enabled in the
®
Novell Internet Access Server Configuration utility (NIASCFG) for each
protocol that needs filtering.
NOTE:
When Filter Support is disabled, the protocol operates as if the filter
module is not loaded, and no filtering occurs. However, the changes you make will
have no effect until you enable Filter Support. When Filter Support is enabled, any
changes you make to the filter configurations take effect immediately. It is not
necessary to use the REINITIALIZE SYSTEM command.
To set up and modify filters, complete the following steps:
1
Load FILTCFG.
The Filter Configuration Available Options menu is displayed.
2
Select the protocol for which you want to configure filters.
The main filter menu for the protocol you selected is displayed.
3
Optionally, for IPX and IP filtering, select Global Logging and select
Enabled to log packets that match the Filters or Exceptions definitions.
