I found in the archive the following message which exactly duplicates my
problem (but , unfortunately for me, I have here the problem, not the answer
I do on the local (10.132.1.154) machine /usr/local/bin/samplicate -S -p
9992 10.132.1.96/9991/1 10.132.1.154/9991/1
10.132.1.154 is the local machine
10.132.1.96 is the cflowd machine.
It seems that on the cflowd machine, I don't receive the flows anymore
Do I have to tell cflowd.conf something about 10.132.1.154 ip address ?
Thanks in advance.

Maybe the packets get dropped by an intermediate router because of the
spoofed source address. Are the original NetFlow source (router) and
the samplicator on the same subnet? It could also be another kind of
packet filter on the router path.

I sometimes use the samplicator in spoofing mode through a couple of
routers and it works ok (although I tend to lose packets from time to
time when I send them through the whole country :-).
