Not able to ping between VMs

[hacknetik1]

Hey guys,

I've upgraded to Fusion 11.5.6 yesterday and i've been having this issue: Not able to ping between 2 VMs.

Host is Catalina 10.15.6

Guest1 Windows 10 DEV

Guest2 Debian (Kali Linux 2020.3)

Both guests are on bridged network.

Firewall and Anti-virus is completely turned off on Windows 10 guest.

I can ping my host from both guests but not between them.

I tried \flushdns on Windows 10 guest.

Windows 10 network is set to public.

Windows 10 ICMP request inbound and outbound are allowed.

It's odd because I had no issue whatsoever before updating.

Please let me know if you need more informations

Thank you!

I've run the commands below and seems to have fix half of the problem. I can ping between the 2 vm but the packet loss is pretty intense.

1. "sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --stop"
2. "sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --start"

H@H:~$ ping 10.0.0.240

Any idea? I've tried resetting the MAC address but still facing the same issue of packet loss.

EDIT: I have to specify that the packet loss is only between the 2 vm. No packet loss with any other devices connected on the network.

Hi hacknetik1 ,

Have you ever set packet loss to the VM? This could be checked via VM settings -> Network Adapter -> Advances Options.
