policy static nat

[giuseppe parlato]

Hello, I have a question regarding policy static nat,

lets suppose I have source 10.1.1.1/32 natted 20.1.1.1/32 with destination 30.0.0.0/8

it means that 10.1.1.1 going to 30.0.0.0/8 will be natted 20.1.1.1 and 30.0.0.0/8 can reach 10.1.1.1/32 through natted ip 20.1.1.1

.. my doubt is .. is that enough (acl applied to nat) or do I also have to apply acl to interface allowing traffic from 30.0.0.0/8 to 20.1.1.1 ?

testing with packet trace seems to be it is not enough.

thanks

Hello,

As long as an outbound connection has been created the returning traffic will be allowed for the existing connection.

Are you using a static policy nat?

Are you trying to innitiate a connection from the other side ( 30.x.x.x)
