Has anyone managed to get NAT on XBOX LIVE to OPEN?

I have a XBOX 360 connected via ICS to Xbox Live and the TEST only shows the NAT as MODERATE.

Ive followed the tuts etc for setting it up for live but it still only says moderate unless I set CF to ALLOW ALL or I set CF to TURN OF NETWORK CONTROL RULES.

Has anyone managed settings using ICS to get the NAT to report as OPEN?

Do you see any blocks in the log?
