DSL network - PPoE Question

My expertise in the PPOE area is lacking.

I have a network (DSL) that is managed (NAT, etc) by a SonicWall TZ170
firewall. As a part of my business, I am often required to run security
scans using Nmap, Nessus, etc against client networks. When I had my
non-stateful Linksys router in place I could scan at whatever speeds my
client networks required. However, the stateful firewall Sonicwall device
has a limit of 6,000 connections and it's killing my ability to effectively
scan - even at the Nmap "paranoid" rate (which doesn't limit total
connections - just simultaneous connections to a single host or target).

My question is:

If I obtain a second static IP from my provider, can I place a hub outside
of my firewall (direct to the DSL modem) and have both the firewall and a
separate PC connected to that hub - each utilizing one of the static IP's?
That way I can run my scans and not be limited by the firewall's connection
limitation, but still keep my main network protected. I'm trying to figure
out if PPoE can run on 2 separate client machines each pulling in a
different IP. My gut tellms me it's not possible.

If so, can an ISP that utilizes PPoE also somehow support a true static IP
address? I can't talk to them until tomorrow and am anxious to get other
insight first..

Thanks..

I don't see why this shouldn't be possible. PPPoE just requires a login id
and password. I'm sure multiple simultaneous logins should be supported.

A true static address? I don't think so, but PPPoE-assigned address that
never changes, is possible. In fact, I once had such a PPPoE address a
couple of years ago.

I don't know what version of SonicOS you have, but you could try using the DMZ.
