NAT vs PAT

[m.metwally]

Dear Experts,

I Have ASA 5510 and I have a limited number of Real IPs, I need to get 3 of my users an access to a service whose their providers asked me for their real IPs to add them to their Access List.

Actually I want to use PATing instead of NATing for this purpose because I do not have enough Real IPs to give it to them.

Do you have anyother IP addresses available other than the "outside" ip address??

If not - a possible solution would still be to PAT, but write an acl that only allows these 3 users to access the external site. Then you only have to give the provide the external IP.

This is not ideal - but it is a solution.
