I have discovered the following regularity: - if source IP address in given pcap is one of "my" IP addresses, then when I try to tcpreplay given pcap, the data is not delivered to applications - if I change all source IP addresses to any other non-local IP addresses (e.g. 10.0.10.6, 10.0.10.7, ... or if I use whatever other address from local network except for my address), then when I tcpreplay modified pcap file, then data is delivered to applications. > >> then when I try to replay the modified pcap file (1.pcap), >> that traffic does reache applications. >> >> I would like to find out the cause of this. >> The only thing which could be causing thing I was aware of was >> "iptables".
