Public bug reported: I found a small bug: ping the external network ip, clear external- gateway and then set the external-gateway back, the ping connection is not recoverd due to conntrack.
here is the detailed operations: 1. make sure a vm is connected to a router: "router1", and the router is connected to an external network. 2. ping the external network in a vm, it should be successful: # ping 8.8.8.8 3. clear the external-gateway, now the ping connection is dropped. # neutron router-gateway-clear router1 4. set the external-gateway back, "public" is an external network. # neutron router-gateway-set router1 public Now, I found the ping connection is not recovered, my investigation shows this is due to conntrack state issue. ** Affects: neutron Importance: Undecided Assignee: Zhao Yi (zhaoyi44) Status: New ** Tags: l3 -- You received this bug notification because you are a member of Yahoo!
