Shared Network not working on Windows 11

Could you share your case ID or the reference to the known issue? We have had this problem in several versions and would like to see a solution or workaround.
The workarounds suggested (Removing the Parallels VrtlIO Ethernet Adapter or giving Full Disk Access) don't work for us.

Somehow the shared network isn't really stable. Now it didn't work again, so I've reconfigured it again (shutdown all vm's and parallels before)

I took 192.168.64.0/24 Subnet (while it's not used in any VPN connections or local networks, mac is connected to) and separated it into two subnets:
192.168.64.1/26 for Host-Only Network and 192.168.64.65/26 for Shared Network.

/26 is 255.255.255.192 mask.

Now com.apple.vmnet.plist contains following

Host_net_address and Shared_net_Address are separated with mask /26.

The network.desktop.xml contains for NetworkID = Shared:
HostIPAddress=192.168.64.65
DhcpIPAddress=192.168.64.65
IPNetMask=255.255.255.192
IPScopeStart=192.168.64.66
IPScropeEnd=192.168.64.126

For NetworkID = Host-Only:
HostIPAddress=192.168.64.1
DhcpIPAddress=192.168.64.1
IPNetMask=255.255.255.192
IPScopeStart=192.168.64.2
IPScropeEnd=192.168.64.62

It works. So far...
 
I've installed SQL on parallels window 11, I just want to access SQLServer Database (Window) from OSX. Although both osx and window are same ip group/ subnet mask, I can not ping window's ip from osx. (CAN pin osx from window). Any advise please.

Hey guys!

After spending much time on this, I could find a solution that still working so far.

For the guys that are still facing this issue, I could solve it by setting manually the IPv4 address/mask/gateway and DNS in Windows 11.
If you are using a VPN in your macOS, you just need to set the DNS manually as the IP from your VPN connection (usually you can find it running an ifconfig in your terminal and looking for the "utunX" where "X" is the ID).

Now I can access the internet plus the internal addresses from the VPN service.

Hope that helps!
 
Hi all, I have tourbleshooted the issue per my side - the problem occurs once the computer was joined to a hardened AD domain. To work properly, ensure that the service "WinHTTP Web Proxy Auto-Discovery Service" (aka WinHttpAutoProxySvc) is not disabled.
 
I still have this problem occurring 18 months later - I am now on an M4 MacBook Pro and it happens there too! Why can't this be fixed?? I have filed at least 3 tech reports.
 
Check your firewall settings to ensure your device or app isn't being blocked. Allow the necessary network ports or apps through the firewall to enable proper traffic flow. If using third-party security software, make sure it's not restricting access.
 
It will work for days and then stop working. Reboot gets it working for awhile. Very few apps are on this VM and they run fine. I did nothing to change default firewall settings, and no 3rd party security software. Plus, it worked for a long time before it didn't with a Parallels update - So imho it's unlikely to be a firewall setting, but thanks for the suggestion!
