[Tcpreplay-users] MAC problem or what?

[<gb...@gm...>]

Hi,

I am trying to use tcpreplay for a network measurement project.
I am basically doing the following:
- capture trace on machine A (1 TCP + 1 long UDP session, all traffic
between A and B)
- modify pcap file to replay traffic between A and C (I had trouble with
tcpprep/rewrite so I used another tool bittwist)
- use tcpreplay on machine A to replay traffic between A and C (hosts are on
completely different network)

As far as I know, rewriting the traffic was succesful, and when replaying,
tcpdump on the replaying machine (A) shows proper behavior.
However I cannot see any traffic on machine C.

>From the archives I see that this is probably MAC addresses of  B and C not
matching.
How can I fix this? I will not know the MAC address of C.

Regards,

G
