The documentation is clear, https://developer.apple.com/documentation/vmnet

"Packets sent from a different IPv4 address are dropped by the system."

But I wanted to have some proxmox nodes (debian with lxc containers) to test and learn high-availability clustering with it

Also it could be cool to use some containers for "micro-services" web architecture

I'm using https://github.com/gyf304/vmcli to create the virtual machines (both x86/arm 64bits are usable), but due to this "single IP" limitation, I can't make a virtual hosts communicate

Is there any option / configuration on bridge100 interface to bypass this limitation ?

The documentation is clear

I believe that comment refers to host and shared mode (VMNET_HOST_MODE, VMNET_SHARED_MODE). A vmnet interface in bridged mode (VMNET_BRIDGED_MODE) can acquire its own IP address from the same network infrastructure as the host, and that IP address isn’t subject to this restriction.
