Map private IP to outgoing public ip address

Posted on 2011-03-03
Last Modified: 2012-05-11
We use a Cisco ASA 5510 in our data center. Admittedly I am not familiar with this firewall at all, working mainly on Fortigate units. I am looking to map one of our private IP addresses to one of our available public IP addresses on our WAN for the purpose of sending out email. I am hoping someone can get me started in the right direction to get this accomplished.

Any idea how to achieve this using the Cisco ASDM 6.1 GUI?

Sorry. It would look like the statement below rather than the one I posted above since you will be using smtp

Command to Enable Nat -->
global (outside) 1 interface
nat (inside) 1 0 0

static (inside,outside) 66.xx.xx.xx netmask  -- This is your NAT statement that you want to add

access-list incoming extended permit tcp any host eq smtp  --- This is your access rule that allows smtp traffic

I am not sure. I have never used the Gui before : -(.... Hopefully someone else can help with that.

Go down to the Configuring Static Policy NAT, PAT, or Identity NAT  section (Figure 21-22) will show how to configure Static Nat through the Gui interface.

The same guide will also show you how to set up the access rule for SMTP through Gui.
