Cisco had a feature in 6.3 that allowed for the mapping of two public IPs to a single private IP. Cisco TAC says that with version 7, that is not possible. I upgraded a customer to an ASA from a 515E that was using this feature and then it broke and their network is down. Is there anyway to be able to do this?
I am looking at this documentation and you can under static PAT configure a single IP address externally that maps to multiple servers internal but they have to be on different ports. http://www.cisco.com/en/US/docs/security/asa/asa71/configuration/guide/cfgnat.html
This customer has two web servers running on the same server with a single IP address. Is there a way to do this with a DNS name?
