How to restrict access from WAN to Zywall?

How can I restrict the access from WAN to my Zywall USG20? I want only be able to have access from the internal network to the Zywall, but not from outside.

Go to Configuration>System>WWW> Create the rule Wan(all address deny)
Therefore, the Wan client cannot access to GUI via Wan IP.

safe_net & @Zyxel_Charlie ,
If you won't provide SSL VPN to Internet.
Then I'd prefer to add one firewall rule to block all HTTP(TCP 80)/HTTPs(TCP 443)service from WAN to ZyWALL.
So that can avoid any port scan tools to detect the ports.
