NAT entry on an a Cisco ASA 5510 to communicate with an AS400


I have moved an AS400 to a NOC.  I have a Cisco 5510 ASA there as well as a switch and the AS400.   The IP configured on the public side of the AS400 is 74.126..x.x and the internal IP is 10.24.x.x
Can somebody please tell me the EXACTLY how to enter a NAT entry via ASDM so that the Public IP is translated to the Private IP.  STEP by STEP instructions are needed please.  I also need to be able to telnet to the AS400 via the internet so Port 23 needs to be open as well.

Thank You

Thank you.

Is the ASA 5510 at the remote NOC side new?

Either way, in ASDM go to the WIZARDS > STARTUP WIZARD and select the option to modify the existing config.
Assuming you have already setup this ASA, you can select Next, and then in step 2 leave everything as is.
In step 3 make sure you check off "do not configure" under DMX VLAN (unless you have previously configured a DMZ). Click Next.
Keep step 4 as previously configured. Click Next.
Keep step 5 as previously configured.. Click Next.
Keep step 6 as previously configured. Click Next.
Now, in step 7 - check off “Use Port Address Translation (PAT)” and “Use the IP address of the outside interface” checked and click Next.
In step 8 - Click the ADD button. Under Access Type, select Telnet. Under Interface Name, select inside. Under IP address enter the local subnet that this asa is on along with the correct subnet mask. Click OK. Ensure that "Enable HTTP server for HTTP/ASDM access" is checked and click Next.
Review in step 9 and click Finish.

You should now configure an ipsec tunnel between the 2 ASA's to make it easy for you to manage.
