Containers have no IPs using OVN network

Incus
,
1

Hello,

I’m trying to use the OVN network in my Incus but my containers don’t get any IPs.
I’m on Incus 6.6.

This is my network configuration

- name: UPLINK
  type: physical
  config:
    parent: br1010
    ipv4.gateway: 10.100.1.1/24
    ipv4.ovn.ranges: 10.100.1.10-10.100.1.100
    ipv6.gateway: fd12:3456:789a:1::10/56
    ipv6.ovn.ranges: "fd12:3456:789a:1::10-fd12:3456:789a:1::100"
    dns.nameservers: 10.10.1.1
    ipv4.routes: 192.168.1.0/24,10.10.1.0/24
    ipv6.routes: 2a01:cb1c:e08:4900::/64,2a01:cb1c:e08:49ff::/64
    ovn.ingress_mode: routed
- name: incusovn
  type: ovn
  config:
    network: UPLINK

So I see my OVN network

But when I start an instance it does not get an IP

incus start c1
incus list
+------+---------+------+------+-----------+-----------+
| NAME |  STATE  | IPV4 | IPV6 |   TYPE    | SNAPSHOTS |
+------+---------+------+------+-----------+-----------+
| c1   | RUNNING |      |      | CONTAINER | 0         |
+------+---------+------+------+-----------+-----------+

My default profile is

- name: default
  devices:
    root:
      path: /
      pool: data
      type: disk
    eth0:
      name: eth0
      type: nic
      nictype: ovn
      network: incusovn

What am I missing ?
I have follow the following instruction How to set up OVN with Incus - Incus documentation

Could be host-size firewalling.

Thank you,

I checked the configuration and I have net.ipv4.conf.all.forwarding=1 in my /etc/systctl.d configuration. So there is probably a problem with docker but I do not know why

I tried the same configuration in another that does not have docker running and the container gets an IPv4 and an IPv6. So, there is a problem with the docker, as say on the page you link.

But I still have other problems now
First, the instance does not have access to internet.

Second, the machine did not get its IPs in the range I defined on uplink
