Has anyone else seen this type of performance hit caused by the TAP

I don't know if this qualifies as a performance hit, but with the TAP
my entire external network goes dead. I've spent many hours trying
all kinds
of stuff and finally gave up. I also have a Broadcom B57 nic, but am
the native driver.

You don't have it tied to a wireless as well do you? If I connect to
wireless it knocks out my whole network, wired and wireless.

I don't think so, as I've never been able to get wireless to work (aside
from your hack of routing through the wired interface)...

Isn't the binding done in VBox itself and not in PROTOCOL.INI?


DriverName = TAP$
HandleArps = 1

And if no VM is running, then it shouldn't matter, should it? That
configuration is stored in the xml for the VM. I ran all of my tests
with nothing else (in terms of networking apps) running.

I was thinking more of the problem Cliff was having, but yes, I only loose the network if VBOX is running and I have wireless turned on in there.
