I have been thinking about using a networks file, although I'm not sure how to do it yet. I have just changed my configuration as follows: aggregate[inbound]: dst_host, src_mac, dst_mac aggregate_filter[inbound]: dst net 192.168.0.0/24 and not src net 192.168.0.0/24 aggregate[outbound]: src_host, src_mac, dst_mac aggregate_filter[outbound]: src net 192.168.0.0/24 and not dst net 192.168.0.0/24 to hopefully exclude local traffic and also to see if some weird MAC addresses are involved, e.g. multicast, spoofing. But I don't see traffic in the gigabytes on either interface when this happens (internal or external).
