I'm trying to open some ports in my ASA 5505 Firewall with the 9.0(1) software. I've being using another ASA with a lower software version. As you can imagine I'm quite confused and have been reading all CLI guides from Cisco and looking at different blogs for help.
I'm trying to open some external ports and trying to map them into my inside servers. I would like to use different ports on the onside and translate them to the original port on the inside.
outside = 220.127.116.11
inside = 10.203.5.1
I'm trying to open for port 10001 and send that into my network while translating it into port 3389. So I'm basically trying to open for multiple servers via RDP but I only got 1 public IP address to work with. I would like to keep the port 3389 on all servers, so when on the inside LAN people can connect to the server without worrying about custom ports. When they are on the outside the have to use 18.104.22.168:10001 to connect to the server through the ASA.
As I understand the commands have changed quiet a bit since I last did the above configuration and that is I'm feeling stuck. I've tried following the examples on this link but without getting lucky. I think i read somewhere that I need 2 objects to do a correct NAT with a PAT configuration or am I way of here?
I would appreciate it if any one could point me in some direction because where I'm now I can't the ASA to do what I believe it is built to do :o)
