[Tcpreplay-users] tcpreplay and routers

[David N. <dn...@ne...>]

How to get tcpreplay working across router hops?

Topology is like this:

10.2.0.0/16 <-> router <-> 10.1.0.0/16 <-> router <-> 10.0.0.0/16

The original pcap has one client and three server addresses, all on
different subnets.

Using tccpprep and tcprewrite, I've changed this so that there's a new
pcap with one client address (10.2.255.254) and three server addresses
(10.0.255.25[2-4]).

Routing works fine, and the hosts at these addresses can all ping each
other.

Problem is, when I replay the pcap there are lots of RSTs coming back
from the 10.0.0.0 side, probably because the servers on those addresses
aren't listening on the port used in the pcap (port 80 in this case).

Do I need to play the pcap on both sides? Or somehow split the flows
apart? Or something else?

thanks
