I have a Cisco PIX 501 curently with a range of ip's configured on the outside interface. These are then NAT'ed through to a coresponding server on the inside were the servers on the inside have private network addresses.
Is there a way that I can configure the PIX to route the public ip's into the inside so that I can configure the servers with there public IP's and have the pix filter the ports that are allowed to pass through? If so how or can you point me in the direction of some documentation.

Cheers Bruce

Short answer - no.
Not with the 501.
With a 515 or higher running 7.x or higher, or with ASA 5500, you can run the firewall in L2 transparent mode. There are tradeoffs like no support for VPN in transparent mode, but you can use the public IP's directly on the end device as you wish.
However, you cannot do both at the same time with some hosts using dynamic nat for outbound and some hosts using transparent mode with their own public ip's.
