You should have a firewall of some type for your own protection. Do you also have any anti-virus softwares? I have heard of AV softw's having a side-effect of blocking b/c they were not properly configured.
I'm starting to have 2nd thoughts about the n-way switch. I was getting confused with something else I think. After having just researched a little about it they can in fact be in process with nat firewalls depending on the device. DMZ setting the way to overcome it.
