Hi there,
We have a new installation of a ASA 5505 and are trying to get some NAT issues straightened out. Here is the scenario: On our internal network, we have two servers running Filemaker Server, a relational database server that clients connect with using port 5003. Our goal is to be able to allow users from the outside to access either of these servers as needed. I know how to set up a simple static NAT rule and matching Access rule in ASDM which would be fine for a case in which only one server using a given port is running on a network, but for simple static rules I seem to be blocked from entering a different translated port number from the orginal port number, which becomes a problem when two servers we need to access from the outside are running software using the same port number.
What is the simplest way to address this need? I am guessing that I need to set up a scenario like this, where port 5004 (or any arbitrarily choosen unused port, can be used to access the second server:
Outside user enters FQDN:5004 and this translates to Database server # 1 as 192.168.1.40:5003
and
Outside user enters FQDN:5003 and this translates to Database server # 1 as 192.168.1.38:5003
If so, what is the easist way to get this done? Or is there a better what to handle this scenario?
Thanks in advance,
James
