Hello Ajit

Locally generated traffic will never be checked by an outbound access list on the interface. Locally generated traffic is traffic that is generated from the same router that has the access list applied.

Take a look at this post for more details.

I haven’t tested this but feel free to try it slight_smile R1(config) control-plane R1(config-cp) service-policy output MY\_POLICY\_MAP Or maybe with some crazy tricks where you redirect traffic like I did in my NAT on a stick example: [https://networklessons.com/cisco/ccie-routing-switching/cisco-ios-nat-stick-c…](https://networklessons.com/cisco/ccie-routing-switching/cisco-ios-nat-stick-configuration-example/)

I hope this has been helpful!
