Hi,
I am running the exception_path application provided in DPDK sample apps on
a 3 virtual machine setup.
VM1 is used for sending icmp traffic
VM2 is installed with DPDK, it has two NICs, one is connected to VM1 and
the other one to VM3
VM3 is used for receiving icmp traffic
Traffic is sent from VM1, VM2 received it and forwarded to the tap
interface as expected.
I want to add iptables(few drop rules) on that tap interface created by
the exception_path application, and check that the traffic drops.
But this is not working, iptables are not being applied on these tap
interfaces.
Do we need some IPStack for example, rump kernel integrated with DPDK to
achieve this?
Is there anything that I am missing here? Basically looking for simulating
firewall using iptables in DPDK.
Regards,
Kanthi
