Ipsec tunnel not working if selected WAN is a PPPoE over vlan

[cotosso]

Steps to reproduce

• create a vlan device
• configure the vlan device with role WAN in PPPoE
• connect it to a valid provider and receive an ip address
• configure an ipsec tunnel with this specific WAN

Expected behavior

IPsec tunnel works flawlessy

Actual behavior

• Web UI shows IPsec tunnel connected, but traffic doesn't flow
• ipsecX interface is not present (tested with ip a command and ifconfig)

Components

NethSecurity 8-23.05.3-ns.1.0.0

After some test I found in the network database a missing reference

network.ipsec1.tunlink='None'

whereas this field should have the WAN interface name. So i set this parameter with the right value e.g.

network.ipsec1.tunlink='Irideos'

and then everything started to work as expected.

I'm not able to verify if the the problem occurs only for PPPoE over a vlan or also for PPPoE over other devices (e.g. physical, bond...)
