Shorewall users - Aug 2003 - suggestion on how to track traffic

Hello,

Is it possible via SNMP to track traffic on secondary interfaces, or is
it only possible to capture the overall traffic?

I''m not very familiar with SNMP, but I''m running MRTG in an
internal host=20
and wanted to be able to capture the traffic data for the secondary
interfaces (virtual IPs) from the lrp box.

Does shorewall keep that information somehow? Is it doable via SNMP, or
is there another way I can do this?

Thanks for any suggestion.

Ricardo
