We are trying to monitor or network address translation (NAT) statistics to ensure that our pools that we define for NAT are large enough. We have 2811 series routers running 12.4.6T7 code. When I poll the device for the MIB cisco-nat-ext-mib, I am not receiving any data for NAT on this router. If I do a show ip nat stat, I can see statistics about nat translations. I am trying to determine if this mib is supported for my hardware platform/code or whether there is a better way to do this via snmp on a management platform
