Yep, you do want tun/tap. But if you create a regular bridge and tells
virt-manager or libvirt to use this for your virtual machines,
virt-manager/libvirt will take care of the tun/tap setup.

>From your virtual machines point of view, tun/tap will get you the
same connectivity as if you plugged a ethernet cable from your network
into it, without any restrictions.
