Last Modified: 2012-05-10
Hi, on Cisco ASA-5505 I have more addresses public and I have a mail server to which is associated with a public IP different from that used by public interface on ASA, for example:

public IP on ASA: IP 88.x.y.1
pubbbli IP on mail server: 88.x.y.2
private IP mail server:

I would that when go to web (on the mail server pc) the ip public address is:
and not: 88.x.y.1

with the current current configuration if for example on the mail server go on I see: 88.x.y.1

Which rule I must add to the current configuration?

Remove all of the individual statics for mailserver and enter a single ip static nat:

static (inside,outside) <public IP2> mailserver netmask

Now all traffic, both inbound and outbound to/from this server will always use the public IP2 address.

after remove all individual statics I must add a new rule as well as in the attached file ?
(where "use ip address" si public_ip2).

You should not have to change the access rules if you are using the same public IP2 as you are using now

sorry but in 'add-rule.jpg' I insert a static nat rule not a new access rule, perhaps I did not understand what that you have suggested to me ?
