Fusion 12 and Host DHCP Issue

[msikscurloc]

Since upgrading to Fusion 12, I've noticed a problem when my MacOS host (Catalina 10.15.7) tries to renew it's DHCP, it either fails or obtains an IP from one my virtual networks.  As soon as I just down Fusion, the issue goes away.

Our DHCP is renewed every 4 hours.  So, as you can guess, I can only have VMs running for as long without having network connections.

Anyone else seeing similar?

There's another thread just posted about a VLAN environment terminating the host lease when Fusion is in bridged mode, so may be related.

Can you try NAT?

Thanks for the suggestions.  Unfortunately, that didn't work.  What I ended up doing is blowing away my "networking" configuration file and had Fusion recreate it.  I lost some of my virtual networks, but it least it seems to be working again.

Hi @msikscurloc 

Do you mean your Catalina host gets an IP from Fusion virtual network? What's the output of command 'cat /Library/Preferences/VMware Fusion/networking'?
