Yes, absolutely. It all depends on implementation. I am using VLANs for L2 isolation. I have a specific DMZ VLAN that has my XMPP server and only my XMPP server on it. My network core applies ACLs that prevent any inter-VLAN traffic from there, so even if STUN/TURN pokes holes, the most that is accessible is that single VLAN, which happens to contain only the single host that I want to be accessible.
Great question.
