Hello, I see a ping not working in below topology with xdp redirect IFACE1 <---------> IFACE2 IFACE3 <------------------> IFACE4 IFACE2 and IFACE3 are on same host machine IFACE1 and IFACE2 are on static ip IFACE3 and IFACE4 are on dynamic ip, IFACE4 runs dhcp server steps 1. assign static ip between IFACE1 and IFACE2 (ex: 172.168.2.x) 2. dynamic ip between IFACE3 and IFACE4 (ex: 192.168.2.x) 3. Run xdp redirect on IFACE2 and IFACE3 4. start ping from IFACE1 to IFACE4
Does IFACE1 have a route to 192.168.2.x and is the next hop resolved? You can use `tcpdump` on IFACE1 and IFACE4 to see what packets are sent and received.
