I replied earlier, but it didn't seem to come through. Anyway, you should use the wildcard mask 0.0.4.255. That will match the addresses 192.17.73.0 - 192.172.77.255, which I think is what you want. In case you don't already have it, download Boson's free wildcard mask calculator at the following link.
