Hi Dennis, Perhaps traffic is VLAN tagged or contains MPLS labels? This can be a possible explanation for filters not working correctly. You can check the tcpdump man page for detailed information about pcap-style filters but as guidance for traffic with a single VLAN tag, ie.:
aggregate_filter[out]: vlan and ( src net <own IP chunk A> .. or src net <own IP chunk Z> ) aggregate_filter[in]: vlan and ( dst net <own IP chunk A> .. or dst net <own IP chunk Z> ) Let me know whether it works.
