How to configure l3ACL dpdk application for gateway

Question

I am trying to configure l3ACL application for gateway.l3fwd ACL Dpdk application is running in Mellanox NIC.using dpdk (dpdk-stable-20.11) as a shared library.

Edit: Earlier scenario of Connection setup of l3fwd acl testing using Trex Traffic generator enter image description here

In this scenario the packets are forwarded by the L3fwd ACL application of DPDK in the direction from Port 1 to Port 0 of the Trex traffic generator. This was made possible by including the MAC address in the --eth-dest flag with the MAC address indicated by the Trex at initialization. On including this MAC address the packets were detected by the Rx side of the traffic generator i.e Port 0.

Current scenario

This setup was modified to mimic gateway level deployment to test L3fwd ACL as shown in the connection diagram attached below.

Connection Diagram attached enter image description here

In this setup the ports connected to the traffic generator are replaced by two machines that mimic the external network and internal LAN network as shown. We have tried to ping the external and internal network without running DPDK application. The ping in the network is working without enabling DPDK. The L3fwd ACL application was subsequently started with the command given below with the physical MAC address of the machine which was replaced at the port 0 side which was earlier connected to the traffic generator. Port 0 received the traffic from the L3fwd ACL application in the case of the traffic generator. The main difference is that we are including a physical MAC address with the --eth-dest flag in the gateway scenario whereas an emulated MAC indicated by the traffic generator was used with --eth-dest flag to forward the packets in the working setup for L3fwd ACL using traffic generator in a loopback manner.

The physical MAC address of the interface of the Rx side of external network machine connected at Port 0 is not receiving the traffic destined out from the L3fwd ACL application. The configured Route entry in rule_ipv4.db is R0.0.0.0/0 0.0.0.0/0 0 : 65535 0 : 65535 0/0xff 0.

Not able to trace the packet at the interface with Mac address given in –eth_dest parameter.After starting l3fwd acl destination host is unreachable. Command used for L3FWD ACL

./dpdk-l3fwd-acl –l 1-7 –n 4 -- -p 0x3

--config=”(0,0,1),(1,0,2),(0,1,3),(1,1,4),(0,2,5),(1,2,6),(0,3,7)” --rule_ipv4=”/root/rule_ipv4.db” –rule_ipv6=”/root/rule_ipv6.db” –eth-dest=0,next-hop-MAC-here
