If I bootstrap three nodes and establish an uplink connection, then try to configure network forward ip, one of the machines becomes unreachable. This issue does not occur with the latest/edge version of microovn

how to reproduce: add a forward ip to a container:
lxc network forward create default 10.205.17.201 target_address=10.99.49.4
Move the container around the cluster and test its reachability until one node is not reachable:
ping 10.205.17.201 PING 10.205.17.201 (10.205.17.201) 56(84) bytes of data. 64 bytes from 10.205.17.201: icmp_seq=1 ttl=63 time=4.12 ms 64 bytes from 10.205.17.201: icmp_se: 3 time=1.60 ms --- 10.205.17.201 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1001ms $ lxc stop u1 $ lxc move u1 --target microcloudp02 $ lxc start u1 $ ping 10.205.17.201 PING 10.205.17.201 (10.205.17.201) 56(84) bytes of data. --- 10.205.17.201 ping statistics --- 4 packets transmitted, 0 received, 100% packet loss, time 3076ms
