Hi everyone I have an issue when setting up the SA 540 Security Appliance with regards to NAT. On our current PIX501 I can map an outside IP to a NAT IP but don't see anywhere within the config to do it on the SA540 appliance. I have added the necessary inbound rules with the ports to the appropriate internal IP but this will not work if the outside DNS is pointing to other REAL IP's other than the IP on the outside interface of the SA540.
so i believe you have multiple public ips and you need the SA to know about these IP addresses. you will need to enter the other IPs under Networking; WAN; IP Alias. enter your ip addresses and appropriate subnet mask. once they are there, when you create the IPv4 rule you will have a dropdown menu at the bottom of the screen with all your assigned IPs. so when you create the SMTP rule you will select 220.127.116.11 on the WAN. that will allow all SMTP traffic attached to that public IP to be forwarded to Exchange.
