Give me a quick reply please..
If I add proper routes in the DUT, then the communication between Client and
Server will be real ??
Does it mean, tcpreplay will start traffic in this order SYN, SYN-ACK, ACK ??.
what if any packet gets missed (ex: SYN-ACK) ??

Did you add new entries in the routing table of the DUT ?
command to be prompt: route ******
on advice: try using tshark instead wireshark.
good luck.

Let me explain how the setup looks like with some more details,
TCPReplay PC DUT
eth0: 10.2.12.156 DUT-eth0: 10.2.12.152
MAC: 44:37:e6:0f:e1:54 DUT-MAC: 00:16:76:c1:32:DA
eth1:192.168.0.100 DUT-eth1: 192.168.0.101
MAC: 00:1c:f0:94:a4:3f DUT-MAC: 00:e0:1c:3c:2f:a6
My application runs on the DUT. The pcap files have Server-Client traffic with
ip addresses, 10.2.12.152 & 192.168.0.101, accordingly the MAC addresses.
This pcap file was pumped from the "TCPReplay PC". Isn't that correct ?? if
not, what change I have to do??
Pls help me.

I changed the MAC address to match the MACs of the DUT. Two instances of
wireshark were used. One listens to eth0 and another listens to eth1.

What is the destination MAC? Could it be that Wireshark is listening in
promiscuous mode but the dest mac is not the DUT NIC's MAC so the NIC and thus
the application don't see the packets?

Hi All,
I am using tcpreplay- version 3.4.4.
The usage is like Client - Server packets go in one interface(eth0), Server -
Client traffic goes in another interface(eth2).
DUT is another PC having two interfaces. Packets sent using tcpreplay are
received in the DUT (wireshark displays all the packets), but my application
running in the DUT does not receive or see any packets.
Why is this behavior ??.
What I should do, so that my application under test can see the packets ??
Any help is appreciated.
Regards,
S. Senthil kumar
