Can you host a server behind a PIX 506 with only 1 public IP?

I have a PIX 506 running 6.11 on a cable modem with 1 static IP. This is on the outside interface and I have it running pat/nat for my internal network 192.168.123.0 255.255.255.0. This works, and I can surf from any pc on my lan.

From my reading here and in the docs it looks like I can push inbound traffic requests (ie web, ftp, etc) to that static IP to a single lan IP. I have included my config attempt to do this below. Any sugestions for makeing this work (or that it won't with just one IP) would be VERY helpful.

Thanks

Miles

FYI I found the problem in a earlier post. Add the following to the above and it works:

access-group 110 in interface outside

Hope this helps others.
