Hi,

I am using tcpreplay for the first time. The version that I am using is 3.3.1.

Basically, I am trying to replay traffic between a linux client and a 
loadbalancer (which does not NAT the server side ip address and which is, for 
all practical purposes, transparent to the client).

Basically, the client sends a HTTP request to the loadbalancer which acts as a 
proxy server to the client. The loadbalancer then sends the request out to the 
real server on the backend.

I have:

client ------------------------ loadbalancer------------------real server
100.1.1.120          100.1.1.5           101.1.1.5          101.1.1.120

So I am trying to replay the traffic between 100.1.1.120 and 100.1.1.5.

The basic issue that I am seeing is that tcpreplay is just replaying the 
capture sequence within the linux box instead of actually sending out the 
packets to the loadbalancer.

I modified the src ip, src mac, dst ip and dst mac correctly to match with the 
client and loadbalancer.

Any idea on what I might be doing wrong ?

I went through the FAQ but could not find the answer.

Thanks a ton,
Shekar.
