Hi,
I’m running on Ubuntu18.04 LXC 3.0.0.
I’ve created 5 debian9 containers with default eth0 networking on NAT:
# lxc network show lxdbr0
config:
ipv4.address: 10.1.1.1/24
ipv4.dhcp.ranges: 10.1.1.2-10.1.1.99
ipv4.nat: "true"
ipv6.address: fd42:6f79:c120:7701::1/64
ipv6.nat: "true"
description: Natted network 0
name: lxdbr0
type: bridge
One of the containers (frontal) has an additional interface configured with:
# lxc network attach vlan7 frontal
# lxc config show kspreprodfrontal
…
devices:
vlan7:
nictype: macvlan
parent: vlan7
type: nic
vlan7 is a flan with id: 7 configured in /etc/netplan/01-netcfg.yaml
...
vlans:
vlan7:
id: 7
link: enp1s0f0
I’ve changed the frontal host internal networking so that eth1 comes first and
default route is going through eth1.
Everything works internal and external…except from time to time, the frontal
starts refusing connexions from the outside for a few seconds (up to 50).
It looks like general networking because all ports suddenly stop working
(connexion refused)
internally the frontal remains reachable
I’m running haproxy on ports 80 and 443, but also tried running apache2 on port
8082. All ports go down at the same time.
Any idea?
Thanks for any suggestion.
Cheers,
Michel
