First, visit forum557 (Cisco Routers).
Other than that, what do you mean by "my script"? Where's the script? Routers don't run scripts, they have configurations. The simple answer is to remove any access-group entries from the interfaces. The default behaviour for a router, unlike a firewall, is to forward all traffic, so that should do what you want.
If this router faces the Internet, I'd strongly suggest using an ACL to limit traffic to the router itself, especially telnet and ssh.
