Re: ntopng & packet filter of libpcap

All packets received come from sFlow protocol activated on remote switches
(3 switches on the LAN). Even if I change IP 192.168.2.10 for 192.168.2.209
which is the one used by the machine where the program run in other to
exclude statistics from this IP (192.168.2.209), I still see it on the
list. So I try to exclude the IP of the probe itself and it still appears
in the result!

The same code.

If you're seeing packets to or from 192.168.2.10, is there some form of
tunneling involved, so that the outermost IP addresses, which the filter
checks, aren't 192.168.2.10, but some innermore IP addresses are?
