10.0.0.0   is a class A address. You are using a class C subnet mask with it. The router is probably configured for classful routing/addressing only. I'm not familiar with the Lucent router and how to configure it, but there should be a command like the "ip classless" on a Cisco that will allow you to configure addresses like that.

The Lucent Pipeline is the Ascend Pipeline.

Since you are trying to filter out a single IP address the netmask is not the usual information to separate network from host, but to separate significant bits from bits to be ignored.  IN this case you want to use a netmask of 255.255.255.255, telling the pipeline that you want it to use ALL of the address bits in determining if a packet is to be permitted or denied.
