Impossible to add good network values "Validation failed: IP address can't be the network or broadcast address" - OVH (ESXI/Proxmox) with screenshots

Support

@filippo_carletti: I have done several tests, I give you the process:

1/ Bug with Cockpit Dashboard Network: Impossible to select the good IP Address / Netmask / Gateway (Validation failed: IP address can't be the network or broadcast address.) and other options (there is only IP address / Netmask / Gateway / Label (optional)).

2/ Bug with the core: The /etc/sysconfig/network-scripts/route-ensXX1 manually route file is removed, I have found to add a “manual” action but it must be “automatic”.

In ESXI, for the NethServer VM:
2 virtual network cards, one for WAN with MAC Address, one for LAN.

Install NethServer “without connection”, after it, connect with root account in console.

WAN:

db networks set ensXX1 ethernet role red hwaddr AB:CD:EF:GH:IJ:KL
 ipaddr XXX.XXX.XXX.XXX netmask 255.255.255.255 gateway YYY.YYY.YYY.254
 onboot yes bootproto none nm_controlled no userctl no
 ipv6init no peerdns no arp yes
 name ensXX1 defroute yes

signal-event interface-update

LAN:

db networks set ensXX2 ethernet role green
 ipaddr 192.168.1.1 netmask 255.255.255.0 gateway 192.168.1.254
 name ensXX2

signal-event interface-update

There is a problem: ip route show:

default via 192.168.1.254 dev ensXX2
192.168.1.0/24 dev ensXX2 proto kernel scope link src 192.168.1.1

It is in the code:

I have done for ensXX1 configuration: defroute yes.

Now, I must to create an action, the ip route del default must not be in this file…

vi /etc/e-smith/events/actions/ovh-route

#!/bin/bash

ip route del default

GATEWAY_VM=YYY.YYY.YYY.254
INTERFACE=ensXX1

cat > /etc/sysconfig/network-scripts/route-$INTERFACE << EOF
$GATEWAY_VM dev $INTERFACE
default via $GATEWAY_VM dev $INTERFACE
EOF

ln -sf /etc/e-smith/events/actions/ovh-route /etc/e-smith/events/static-routes-save/S33ovh-route

chmod 0554 /etc/e-smith/events/static-routes-save/S33ovh-route
chown root:root /etc/e-smith/events/static-routes-save/S33ovh-route

signal-event interface-update

ip route show:

default via YYY.YYY.YYY.254 dev ensXX1
YYY.YYY.YYY.254 dev ensXX1 scope link
192.168.1.0/24 dev ensXX2 proto kernel scope link src 192.168.1.1
