Allowing a range if IP addresses through an ASA using ASDM

Hello Experts,
I’m sure this is a lame rookie question, but I’m a total Cisco ASA rookie, so I’m going to ask it any ways.  We have a Cisco 5520 at work.  Some users are trying to test new software and things are not working.  I have contacted the vendor and they have said we need to open five different ranges of IP addresses.  I don’t know how to do this.  I’m using the Cisco ASDM because I can’t seem to find any of the access rules in the Cisco cli.
Here is what I think I need to do (again, this is from within the ASDM (sorry about that)):
1.      Create a new network object group that contains the IP ranges that the vendor said I need to allow through our firewall
2.      Go to the Advanced ¿ ACL Manager
3.      Create a new rule in the from_out section where the source is the group I created in step 1 and the destination is any.

Does this sound about right?

As always,
Nick

The configuration all depends on how traffic will flow, and not just the endpoints. Try to draw us a picture if you could. Also add in who will start the conversations so for example the average user will communicate with the internet but people on the internet should never be able to directly connect to that user. Likewise, a web server might need general access to the internet AND allow random internet users to connect directly to it on ports 80 and 443.

This explanation will help us help you.

We have users that are going to log into Skillsoft.com (which I believe is a web-based training site).  When they try to log in, the connection just stalls at the login screen.  I have contacted their support and sent them logs regarding our Java installation.  They have come back and asked that I open the following IP address on our firewall:

209.235.8.1 – 209.235.9.254
209.235.10.1 – 209.235.10.62
209.46.44.1 – 209.46.45.254
216.205.88.1 – 216.205.91.254
216.245.129.113 – 216.245.129.118


I hope this helps.
