Hi, currently my setup is round robin (active/standby) with mirror traffic replication. I tried to duplicate port udp 9000 and supposedly both server receive the packet but only active server will reply. But right now the problem is the other server doesn’t receive any duplicate packet udp port 9000. Can someone help thanks
