Unsure what you meant by this. In a multi-tenant firewall
implementation (as far as I envision it), all tenants would
occupy different IP space so I don't get how any of the
state sessions would be affected. I'd be more concerned
with not enough sockets. 

Palo Alto has a virtual system set up built specifically
for this:

Now if only they'd send me free firewalls for marketing
them.
