I've been trying for a while to figure out if NFDUMP will allow me to tie
the pre and post NAT traffic together. A recent recomplie has added a X-src
and X-Dst (I think this is for Cisco ASA).
I am using Cisco IOS with Netflow v9. I compiled nfdump with
--enable-nfprofile --enable-nftrack --enable-nsel and --enable-sel.
Thanks for any help.
