Can a ASA 5510 NAT one public IP to two private IP's?
I ask becasue I have a Symantec Mail Security 8300 that recommends you assign two seperate IPs to the NICs. One for outgoing mail and one for incoming. I would like to place the one of the NICS in a DMZ for incoming SMTP. then the other on my LAN for mail delivery to the exchange servers.
would i need two seperate translation rules, one for incoming (MX ip to dmz), and one for outgoing mail (LAN to MX ip)?
If i understand correctly you are placing Symantec Mail Security 8300 in the DMZ .This device will be receiving all the emails on external NIC and then this device will be forwarding mails to Mail server(in DMZ) using internal NIC. if this is the case then you just need to map external NIC ip to public ip.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
