Close all WAN ports on Technicolor router in default AAISP config

Hello, please can you change the default config of the new technicolor routers so that all the WAN side ports are closed when I plug it in first time. My new router was delivered with Telnet, HTTP and HTTPs ports open the WAN side. Tech support havn't been able to help me, so I googled and used the CLI on the router to manually close the ports.
