nordvpn whitelisting 2 subnet LAN hierarchy

I have a network setup like this:

Ubuntu Laptop (192.168.1.157) --> Router B (192.168.1.1) --> Router A (192.168.0.1) --> Internet

and

CIFS NAS drive (192.168.0.50) --> Router A (192.168.0.1).

When vpn disconnected, laptop can ping any 192.168.0.* devices and it can access the NAS drive.

On the laptop, I've created nordvpn whitelist for all local addresses:

> nordvpn whitelist add subnet 192.168.0.0/16

The resulting setting:

> nordvpn settings
Technology: NORDLYNX
Firewall: enabled
Firewall Mark: 0xe1f1
Routing: enabled
Analytics: enabled
Kill Switch: disabled
Threat Protection Lite: disabled
Notify: disabled
Auto-connect: disabled
IPv6: disabled
Meshnet: disabled
DNS: disabled
Whitelisted subnets:
        192.168.0.0/16

So now, when it is connected to VPN, the Laptop can ping

192.168.1.* devices
Internet addresses (1.1.1.1, www.google.com)
But NOT to 192.168.0.*

Versions

OS Ubuntu 22.04.2 LTS

Kernel 5.19.0-32-generic

NordVPN 3.15.5

What can I do to get my laptop see the NAS drive?

Note 1: I know I can just move the NAS drive to same subnet 192.168.1.0/24 to get it working but I'm curious what's stopping the traffic to the upper level of a local network.

Note 2: I've already chatted to NordVPN tech support and didn't reach a solution

Can you share the output of `ip route` before and after establishing the VPN connection? Do you have a static route for 192.168.1.0/24 on router A (pointed at router B)?

here's the output: ❯ ip route default via 192.168.1.1 dev wlp1s0 proto dhcp metric 20600 169.254.0.0/16 dev wlp1s0 scope link metric 1000 192.168.1.0/24 dev wlp1s0 proto kernel scope link src 192.168.1.157 metric 600 I don't have any static routes configured (I don't even know how)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
