We are setting up a streaming service to an external client and they need access to an internal workstation along with certain ports open on our firewall. I need to configure two public IP addresses on a PIX 506 to map to two internal private addresses. My understanding, weak at best, is the 506 only has one outside interface and that is already assigned a public address.
Our PIX is no longer supported by Cisco, so I am not able to use our Smartnet contract to get help for this configuration. While we do have several other devices under contract with them, they are not 506's and they won't help us out with the configuration.
I have the ports I need to open and I think I know how to write the access list to allow them through(one example):
access-list outside_access_in permit tcp any host <IP address> eq 389 static (inside,outside) tcp <IP address> 1718 172.16.4.211 389 netmask 255.255.255.255 0 0
My question. Do I just add the public IP addresses I want to assign in the IP address field, for each address and protocol, or do I need to do something else or am I not able to do what I want?
Please let me know if I need to provide anything else as far as configuration.
