Are there any gotchas when trying to configure this?
I tried to configure this using:
global (external) 1 x.x.x.66
nat (inside) 1 0.0.0.0 0.0.0.0
And I was not able to ping any external devices. However, prior to this configuration, we had another device that would NAT the internal IPs in front of the ASA and we were able to get external.
Also on top of the gotchas, are there any ACLs or configurations that commonly affect the NATing ability of the ASA?
