I am attempting to collect NAT logging from a CGN router using BPA.
For whatever reason, nfacctd never seems to see the incoming packets as
flows. (flows always 0)
All I really want to do at this point is collect the Netflow records
coming in and just drop them in a log (for now). Once I can manage to
get that working I may work on a pgsql DB.
The data is getting to nfacctd but I'm unsure what the problem is. I
have tried the memory plugin as set, attempting to view collected data
there, and the list also always empty...
More info:
