Yes, it is entirely possible to create an ACL that matches all traffic types by using an "any" condition—such as permit ip any any in standard network operating systems like Cisco IOS. If you are encountering configuration errors, it typically comes down to platform-specific syntax, applying the rule to the wrong ACL type (e.g., mixing Layer 2 and Layer 3), or hardware limitations on certain ports. Double-check your device's configuration guide for extended or IP-named ACL syntax to ensure the universal matching statement is permitted in your specific context.
