| sasukeh | Hello, I have question about neutron HA. Why l3 HA doesn't suport UDP and ICMP connection track function. I've referred to https://wiki.openstack.org/wiki/Neutron/L3_High_Availability_VRRP say like this. conntrack template doesn't have allow protocol UDP and ICMP | 16:20 |

| *** dgurtner has quit IRC | 16:21 | |
| aspiers | sasukeh: conntrack is for stateful connections, UDP/ICMP are stateless | 16:48 |
| aspiers | sasukeh: L# HA does support all IP | 16:48 |
| aspiers | s/L#/L3/ | 16:49 |
| sasukeh | Protocol Accept { | 16:52 |
| sasukeh | TCP | 16:52 |
| sasukeh | UDP | 16:52 |
| sasukeh | ICMP # This requires a Linux kernel >= 2.6.31 | 16:52 |
| sasukeh | } | 16:52 |
| sasukeh | aspiers: you mean the template modify to like above? | 16:52 |
| sasukeh | aspiers: you mean can the template modify to like above? | 16:52 |
| aspiers | probably, I never used conntrackd | 16:53 |
| sasukeh | okay, then we will need more discussion about this. my customer mention number of ICMP packet drop with l3 ha function of neutron. I think it would be related to this. | 16:54 |
| aspiers | I doubt it | 16:55 |
| aspiers | maybe it's possible, difficult to say without more info | 16:56 |
| aspiers | http://www.iptables.info/en/connection-state.html#UDPCONNECTIONS | 16:56 |
| sasukeh | Thank you for that information. I'll check it later. | 16:56 |
