Hi there,
If I have a combination of both static address translations and a global & nat address translation for the same public ip address, which rule takes precedence. Static or global & nat.
This is a purely academic question.
Thanks in advance.

Hi,
Static takes precedence , then nat0 with access-list then nat/global, then nat0
Thanks

Actually, one minor correction here for documentation sake:
NAT ORDER OF OPERATIONS
The rules are tried in order.
1) nat 0 access-list (nat-exempt)
2) match against existing xlates
3) static
a) static nat with and without access-list (first match)
b) static pat with and without access-list (first match)
4) nat
a) nat
b) nat
Note: When choosing a global address from multiple pools with the same nat id, the following order is tried
i) if the id is 0, create an identity xlate.
ii) use the global pool for dynamic NAT
iii) use the global pool for dynamic PAT
5) Error

Hi Scott,
Yes you are absolutely right, thanks for the correction.
Thanks
