I have a Pix 501.  I need to map a public IP address to a private IP address.  I have a remote user that needs to print to a printer on the local network.  She was working through a VPN, but because of changes on her local network, the VPN will no longer work for her (and this is no longer an option any more).

Have attempted to set up port forwarding or NAT? If not you can do this to allow connection.

I am not sure why you say their remote network has changed on broken the VPN.  If the remote user has a home router, VPN pass thru if enabled, should take care of any changes they make remotely.

NOTE: this could be a dangerous move tho as you will be allowing access to anyone. Also, the remote user at home is provisioned dynamic IPs so if you wanted to do this the remote IP would changed constantly.

The remote user (an accounting office) has a lan to lan vpn using a PIX on their end.  Their company does not want to set up a lan to lan to our network.

I believe NAT is what I am looking for.

OK then if that is the case, you should be able to setup NAT at both ends for user to connection specific to that user as long as you have the available public IP other than your general users' gateway.

None of these worked.  Even after working with Cisco TAC, we were unable to come up with a solution that would solve my needs.  Thanks for your help.
