Cisco ASA 5510 configuration questions

I recently purchased a Cisco ASA 5510. I have not worked with Cisco products since 2001 and have a few questions. First i will give you my current setup:

1 Domain Controller - DNS, File server standard network, .254 being the gateway or the router, .1 being the PDC.

I need all outgoing traffic enabled
I only need to allow port 3389 for one external user

I will also be setting up VPN with a few 5505 in the next couple of weeks, but for now, i really need to make sure the initial setup is correct on the 5510. I am using the ASDM because my command line is very rusty.

Any help is greatly appreciated. Thanks in advance.

What version of the ASA software are you using?

Plug a laptop into the management port of the asa and browse to (it is the default address, and has DHCP).

Download and install (or run Java) ASDM.

You can run through the startup wizard to configure the interfaces.  Sounds like you'll only need one access list, with one line allowing 3389/tcp in on the external interface.

Once you have your interfaces setup, configure a different IP range for the management interface, or just unplug it.  Make sure you can access ASDM from your internal range.  (device management, management access).

Let me know what step your at, and where you need more help.

thanks for the quick response

On the 5510 i have ASA Version 7.0(8) and ASDM Version 5.0(8). I have done a few configurations through the is what I have so far:

Interface ------Name ----- Enabled - Security Level ----- IP ------ Subnet -------- Management only - MTU
Ethernet0/2 disabled

I also setup to use PAT to point outgoing traffic to the WAN IP. I also am attaching a word document showing the two security policies setup, one by PAT and one by adding 3389.
It doesn't look quite right, but that ASDM is quite old, and I don't have access to one to see what it should look like.  

Can you paste the running config?  You should be able to do File, show running config in new window, or download running config.  

I'd also recommend upgrading to either 7.2(4) and ASDM 5.24 or ASA 8.0(4) and ASDM 6.2.1.

Here is the running config, i only x'd out the username password and WAN ip. also, i downloaded the ASDM 6.2.1 bin file, how do I upload that to the 5510?

Also, I can only log in to the ASDM through the management port, i cannot login through the LAN0/1.
To upgrade, you need to copy both the new ASA os file, and the ASDM file.  (Each os has a corresponding asdm, you need BOTH or you won't be able to log into ASDM).  You should be able to upload them through the tools menu, Upgrade Software, or file management.   You can also copy them logged into the command line "copy tftp flash" and answer the prompts.  This requires you have the files stored in a TFTP server directory on a local machine.  Solar Winds offers a free TFTP server. (Like FTP, but no authentication/etc)

To log into the ASDM from your internal network, you need to add http access. In ASDM, look for 'device access' and 'https/asdm'.  You need to specify an IP allowed to connect, and an Interface. (internal IP address / LAN0/1)
You currently have: 'http LAN0/1'
It should be:              'http LAN0/1' s
This will allow asdm access from the internal network.  (or you can specify a single IP with
1 ip:             http LAN0/1

your access is: access-list WAN0/0_access_in extended permit tcp interface WAN0/0 object-group RemoteDesktop host

it should look something like this:
access-list WAN0/0_access_in extended permit tcp {external host IP} object-group RemoteDesktop host {terminal server Public IP}

sorry there hasn't been an update. The flash ended up being bad and I had to RMA the unit. As soon as the new one comes in, I will reconfigure it and post the running config.
