Reference Guide for the Model RT338 ISDN Router
Applying the Filter
When the filter design is finished, you must tell the router where to apply the filter. Apply it as a
Call Filter in the remote node that reaches your DNS server(s) (usually your ISP node). Go to
Menu 11.1, Remote Node Profile, and toggle "Edit Filter Sets" to Yes by using the spacebar.
This brings up Menu 11.5 - Remote Node Filter. Enter the number of the filter under "Call Filter
Sets" protocol filters as shown in
four by entering their numbers separated by commas.
