Disconnecting Network in Hardware Configuration Does not Fully Disconnect the Network.

• Parallels Desktop 26 for Mac
• Pro Edition
• Version 26.1.2 (57293) and Version 20.2.2 (55879) and others.

Problem:
Parallels 26.1.2 with macOS Guest with network configured to "Source: Disconnected" is NOT disconnected from network.
Steps to reproduce:

1. Start up a VM of macOS 13, 14 or 15 with Network Source selected as "Shared Network (Recommended)".
2. Confirm network connectivity by pinging the IP address 8.8.8.8. Also note that "ipconfig en0" shows "status: active".
3. Disconnect the VM from network by selecting "Configure->Hardware->Network->Source: Disconnected".
4. Confirm network is disconnected by trying to ping 8.8.8.8 and observing "Request timeout for icmp_seq 0 .. 1 .. 2 etc". Also note that "ipconfig en0" shows "status: inactive".
5. Reboot VM.
6. Here is where the problem is. Confirm network connectivity by pinging the IP address 8.8.8.8. Also note that "ipconfig en0" shows "status: active".
7. Verify "Configure->Hardware->Network->Source: Disconnected" so should not be able to ping anything.

Alternatively, Shutdown the VM and select "Configure->Hardware->Network->Source: Disconnected" in order to do a textbook Network disconnection. After booting the VM, you will find limited network availability with ifconfig en0 showing "status: inactive".

Was NOT able to reproduce with Windows VMs.

I am coming from VMware where disconnecting the network yielded absolute results. Was hoping for same with Parallels?

Anyone else seeing this problem?
