I know why you’re here. It’s a pain isn’t it?
Let’s get this sorted for you (and me sometime in the future!).
Assumptions:
* You have attached your failover IPs to the server
* You have generated a MAC address for the failover IP (02:xx:xx:xx:xx:xx)
You will need the failover IP (the one below is an example)
192.168.0.20
Here is my configuration:
/etc/netplan/00-installer-config.yaml
# This is the network config written by 'subiquity'
network:
ethernets:
ens18:
addresses:
- 192.168.0.20/24
gateway4: 192.168.0.254
nameservers:
addresses:
- 208.67.222.222
- 208.67.220.220
search:
- virtual
version: 2
As you can see, I just changed the /32 to /24 and changed the last octet of the gateway4 from 120 to 254.
The key is the /24 part. If you leave it as /32 it thinks the gateway is on a separate network.
This does work with real OVH failover addresses, I only used the internal network address 192.168 as an example.
