Hi @SivaM 

Thanks for posting in our business forum.

Here are some you could try:

1. Refer to the ACL guide we have on the forum. There was a case where ACL applied for the WG scenario.

2. At least a diagram should be posted to show how you would like to the ACL networks.

3. WG access is controlled by its routing table. And you should pay attention to how you configure the Allowed IPs as I have specifically explained this part. Instead of using the ACL, you should examine how you set that part up.
