Thanks for the responses. You've confirmed what I had passed to mgmt. But I still have a problem (with mgmt) 
understanding why?...

I perform vulnerability analysis on our outside (public) web presense, usually during development and then after it's 
been deployed. I basically use the same tools for each.

Mgmt wants me to only test through the firewall as if I'm coming in like the public. The rational is that the fw will 
prevent any attacks though ports other than 80 and 443. Therefore, there is no reason to change this configuration.

What would be the reason to test behind the firewall?

that there are other vulnerable systems or servers running on the same subnet, or that web based applications are vulnerable to attack. Prot 80 and 443 are not just plain safe in and of themselves. Especially with everything thazt tunnels over those ports these days.
