Hi, I have a KVM guest VM with a total of 4 IP's, 3 public(belong to the same network) and 1 private.
NIC0: XXX.XXX.XXX*.27 * NIC1: 172.XXX.XXX.XXX (private IP) NIC2: XXX.XXX.XXX*.127* NIC3: XXX.XXX.XXX*.137* The first public IP(XXX.XXX.XXX.27) works fine but the second(XXX.XXX.XXX. *127*) and third(XXX.XXX.XXX.*137*) doesn't work. Both the IP's start working If I delete the flow rules for their in_port(823 and 824 here). Below is the dump of OpenvSwitch flows for the 3 interfaces belonging to these 3 IP's *Working Interface flow NIC0* NXST_FLOW reply (xid=0x4): cookie=0x0, duration=1066.314s, table=0, n_packets=1298,
