Per the FAQ: http://tcpreplay.synfin.net/wiki/FAQ#Doestcpreplaysupportsendingtraffictoaserver
You can't use tcpreplay to send TCP traffic to a server (like a web server). That's why you're getting the RST packets. If you want to send traffic through the routers, yes, tcpreplay can do that. You'll first need to run tcpprep to split the traffic into the client and server flows and then use tcpreplay to send the traffic. The caveat is that you'll need one computer with two NIC's connected to either side of the routing path. All the above is documented in the manual, so I continue your research there. -- Aaron Turner http://synfin.net/ Twitter: @synfinatic Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. -- Benjamin Franklin On Wed, Apr 2, 2014 at 10:04 PM, David Newman <dnew...@networktest.com> wrote: > 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?
