SSL-VPN behind a other Router

I want to create an SSL-VPN conection between my Computer and my Zywall VPN50. The Zywall is behind a Router. Which Ports do I have to forward and what do I have to change in my router so that it forwards the Traffic to the Zywall? The Zywall is configured as a DMZ in the router and every device at home is connected to the Zywall and not to the router. The DDNS is already configured and I already configured the SSL-VPN.!gwsViewDetail.action?articleOid=015546&lang=EN

    Did you configure the Nat rule and security policy on your own device(fritz!box)?
    I have confirmed on my lab with two USGs and the scenario is working.
