[SOLVED] Allow a host to connect only to a single destination

[kalsan]

I have two virtual machines, let's call them A and B. A is connected to the internet through virbr0. Now I want to configure Proxmox in a way that B can connect only to A, but to no other host on the LAN or WAN.

How can this be achieved? Thanks in advance.

Oh man. Never forget the obvious option.

-> Create a bridge virbr1, leave unconfigured (all fields but name empty!)
-> Connect A to virbr0 and virbr1 and B to just virbr1
-> No need for the hassle of setting up a DHCP server, simply set all connected machines to manual static IPs
-> Done :-D
