Hi: I had question on the working of PAT.
I have one Public IP address, I would like to perform PAT. The Firewall is not allowing me. Is there a way to configure PAT with one Public IP address. This Public IP address is also the external interface IP address.
would appreciate the help
thank you

Hi,
The two lines below (which you have) will do PAT with one public IP
global (outside) 1 interface
nat (inside) 1 0.0.0.0 0.0.0.0
However I'm not sure what this line is doing as the ACL doesn't exist
nat (inside) 0 access-list inside_nat0_outbound
Nat 0 statemnts with an ACL are processed first, if there is no ACL then i'm not sure what the behaviour might be (accept all or deny all?). Try removing this line from the configuration

thank you James.
I will remove the NAT statement.
Do i need to define Public IP address?
example
global (outside) 1 10.1.1.254
thx

Hi,
If you want your PAT IP to be different than the interface IP then you define it.
However as you only have one public IP then just use the interface option ie
global (outside) 1 interface

BTW, please post to say if this solves your problem as I would be interested to know.
Thanks
