Hi, Assuming you have the CS with two isolated network VRs prj01A and prj02B. You are sending traffic from the VM02B to VM01A. Hope you configured the NAT rules to reach VM01A.
VM02B ----(guest)eth0 (prj02B VR) eth2 (public) ---------------Hypervisor------------eth2(prj01A VR)eth0-----VM01A In the above traffic path you can also capture the traffic the VM/VR vif on the hypervisor.
