I currently have an ASA5510 that has it initial IP block being provided by the DC, recently the company has had a need for a new IP block which has been given to us by the same DC but is also discontiguous from our original block. I have ponder best possibilities to configure the outside interface to accept the new block but wanted to get some other opinions. Any ideas would be greatly appreciated.
You can use them until and unless those public ip's point towards the ASA outside interface by your service provider, it shoudl be fine, you can configure them on the ASA.
Yes that will work SP route pointing to your interface will bring traffic upto your outside interface of Firewall and based on your requirement you can allow traffic by using ACL. Nothing much is really required.

So essenstially nothing fancy really needs to be done so the ASA recognizes the new block. As long as the SP routes that block to the external inteface of my ASA and I create rules to allow the IP block through it will work?
