Cisco ASA 5505 with two internet connections; publish a mail server.	Darth T	06-03-08

I have a Cisco ASA 5505 with security plus licensing, an Exchange
Server and internet connections.

Here is what I need. The "outside" interface is connected to my DSL
modem and has an IP address of 1.1.1.1. I want to use this DSL
connection for web browsing.

The "inside" interface has an IP address of 192.168.0.3, my email
server has an IP address of 192.168.0.246 and is connected to the
inside interface by a switch.

The "public" interface has an IP address of 2.2.2.2. This is the IP
address I want people outside of my network to use to access my email
server. When users try to access my email server their traffic will
be addressed to 2.2.2.2. When the traffic reaches the firewall there
will be an access-list to allow the traffic in. There will then be a
static rule to translate/route/direct the traffic to the email server
at 192.168.0.246. When responding, the email server send the
responding traffic out the "public" interface.

I am doing this right now on a Sonicwall 2040.
