I have tried what you say, but ping doesn't works between host and guest. If I put an ip to the bridge works ok, but not when I assign an ip to tap interface. > > > > > > Any idea why?? > > > > Are you using IPs from the same subnet on host and in a guests?

When I assign IP 172.22.55.1 to the bridge on host side, host and guest can communicate. But when I assign 172.22.55.1 to a tap interface on the host and create a bridge with host's tap interface and guest's tap interface, there is no comms between them ...
