Hi,

I'm running tcpreplay 4.0.4 on Ubuntu Linux 12.  I've read the usage
examples (http://tcpreplay.synfin.net/wiki/usage) and followed along.  I'm
trying to replay a single-stream (one 5-tuple) pcap so that packets go
through a router.

My hardware setup is involves one Linux machine (with eth0 and eth1) and
one router (which does NAT):

     eth0 <-> LAN (router) WAN <-> eth1
192.168.0.1 <-> 192.168.0.2 (router) 10.0.0.2 <-> 10.0.0.1

* Will this physical setup work? Or are there common pitfalls or mistakes?
* For packets that have src IP 192.168.0.1 and dst IP 10.0.0.1 (both on the
linux machine), will the Linux OS short-circuit and simply pass packets
internally (and not actually send it out to the router?)?


If I can get tcpreplay to actually send packets from a pcap through a
router I will donate $ to whoever or whatever, because this will be the
most useful tool.  It's something I have needed for such a long time, and
will get used a lot.

Thanks ahead for any help,
Mike
