I have a general NAT question I hope you can help us with. We are converting from a large public ip address block (no NAT whatsoever) into a private address space using a combination of NAT / PAT, etc.
I think the ASA can do this without issue (version 8.04), but want to verify. On the Outside interface I have a completely different subnet than the public space I have inside. (Basically a /30 on the outside to the provider and a large /19 on the inside). Now, can I NAT this /19 to the Outside interface even though is is on a different subnet than the /30 assigned to the Outside?
Example (ip's changed to preserve the innocent):
Outside IP = 220.127.116.11 /30 (apologies to whoever owns this space)
Inside IP = 18.104.22.168 /19 (more apologies)
Can I NAT that 22.214.171.124 /19 to the Outside without issue?
Thanks for your assistance!
