What steps will reproduce the problem?
1. Goto Diagnostics->Detailed Statistics on the routers web-page
2. Connect with putty to router and execute command ifconfig

What is the expected output? What do you see instead?
The Receive Total and Transmit Total items on the router web-page do not 
correspond with the values from command ifconfig

It is normal if the Hardware NAT works.
2130 default turn on the Hardware NAT engine.
CPU don't know the traffic through HNAT.
So the ifconfig (by CPU) statistics is less then WUI statistics (by switch 
chip).

As a consequence also the SNMP values are affected. Which makes graphing 
traffic "not usable" when using NAT.

How can one see via command line the "real" traffic?
Is it also possible to add the values to a SNMP tree?

Where you able to solve this?
I'm trying to use Cacti too, but so far only strange values :(
