Reference Guide for the Model RT328 and Model RH348 ISDN Routers

5.Define the next five rules the same way—one for each combination of the three port numbers and the two protocol types.

The last rule, however, will be slightly different. For Action Not Matched, select “Forward.” Any packet that has not matched any of the six rules will be forwarded for routing.

When all six rules are defined, Menu 21.1 should appear as it does in Figure 8-5. As a visual check, make sure that all six rules contain “Y” in the A (Active) field, “D” (Drop) in the m (matched) field, and “N” (next rule) in the n (not matched) field, except for the last rule, which should have “F” (Forward) in the n field.

Figure 8-5 shows the Filter Rules Summary menu with all six rules defined.
