Parallels 17 does not connect host Mac to shared and host-only networks

Since upgrading to Parallels Desktop 17 (and/or moving to macOS 11 and now 12), my host Mac does not connect to the Parallels shared and host-only networks. In older versions of Parallels, there was a checkbox in the Preferences > Network settings to indicate you want to host Mac to connect to these networks. That setting is not present on Parallels 17.

Guest machines are assigned the appropriate IP addresses for the network adaptor selected. But when using shared networking or host-only networking, I need to be able to connect back to the host via IP address (e.g, to a Web server running on the host Mac), especially when I am in a location where I don't have internet access.

How do I get the Mac to get connected to the Parallels provided networks?

Parallels version: 17.1.1 (51537)
Mac: MacBook Pro (2019) with Intel chip; running macOS 12.1 (Monterey)

The shared network and host-only network appear to be bound to virtual NICs on the Mac:

Code:

% prlsrvctl net list         
Network ID        Type      Bound To
Shared            shared  vnic0
NAT server:

Host-Only         host-only  vnic1
en5 (en5)         bridged   en5
Wi-Fi (en0)       bridged   en0
awdl0 (awdl0)     bridged   awdl0
llw0 (llw0)       bridged   awdl0
USB 10/100/1000~  bridged   en9
vnic0 (vnic0)     bridged   vnic0
vnic1 (vnic1)     bridged   vnic1
Default           bridged   FF:FF:FF:FF:FF:FF

But I don't get IP addresses assigned to the Mac:

Code:

% ifconfig
...
vnic0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    options=3<RXCSUM,TXCSUM>
    ether 00:1c:42:00:00:08
    media: autoselect
    status: active
vnic1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    options=3<RXCSUM,TXCSUM>
    ether 00:1c:42:00:00:09
    media: autoselect
    status: active

Thank you in advance for any assistance.

 

Hi, kindly refer to this KB article for resolving the issue.

 

@DebasmitaM@Parallels, thank you for the response. The KB article you pointed me to does not address the issue I am having. My guest VMs (such as Windows 10) are getting assigned an IP and can access the internet just fine (along with other guest VMs using shared networking).

What is NOT working is that the Parallels HOST (that is, my Mac) is not getting assigned an IP for the Parallels-created subnets. So I cannot access the host Mac from the guest machines.

In previous versions of Parallels, the host Mac would get assigned IP addresses 10.37.129.2 and/or 10.211.55.2 and I could use those addresses from a guest Windows VM to connect to the Web server on the Host Mac. But that IP is no longer being assigned to the host Mac. See results of a ping from the Windows guest VM to this IP:

Any ideas on why the host Mac cannot connect to these Parallels-created subnets?

 

Hi, please follow the knowledge baser article https://kb.parallels.com/6571 to create a support to assist you further.

 

Hi, what was the fix here? Getting the same problem. It was working before.

 

No fix yet that I am aware of. They wanted me to put in a support ticket on the issue to get assistance. I had gotten used to living with the way things were and haven't gotten around to creating the support case.

 

@JonL8 @StevenD8 are you still having this issue? I had the same issue but resolved it by doing a few things, I'm not if all steps are required:

1. Uncheck "connect mac to this network" on all networks listed in Preferences -> Network
2. (test -- still not working)
   
3. sudo ifconfig bridge100 down
4. sudo ifconfig bridge100 up
5. sudo ifconfig bridge101 down
6. sudo ifconfig bridge101 up
7. (test -- still not working)
8. restart parallels
9. (test -- working!)

In my case bridge100 == shared network and bridge101 is my host-only. If you have more than two bridge networks you will need to find out what ones are owned by parallels.


I wonder if it would be enough to just check/uncheck/restart? Or maybe ifconfig down/up restart?

 

I had the same issues.
ifconfig on mac shows that ip is assigned for bridge101 but not for bridge100.
I've toggled off/on Parallels setting 'Connect Mac to this network' for both Shared and Host, restart Parallels and wow! bridge100 also has ip.
