NAT not working on my ATP200

this is my topology. 
ATP200 has firmware 5.10(ABFW.0) , FLEX 200 has firmware 5.10(ABUI.0)

i have setup SSL vpn on flex200 with port 4430

on ATP200, i have configured NAT TCP port 4430 to forward to my flex 200, it did not work. I tried to plug my pc to ATP200 LAN interface and ssl vpn to flex200, it works.
Using SSL vpn by connecting from Internet does not work.

here is the NAT setup i did on my atp 200

because NAT is not working, i have disabled policy control under security policy on both devices.

Can you help on this issue please?
Thank you

    Odd I have a setup that does the same thing and works but with other ports/IPs and zywall 110 to USG40.

    Have you used External IP for NAT is interface type for WAN1 IP instead of IP?

    Can you run a packet capture of the atp 200 for WAN1 and port scan 4430 to be sure its hitting the WAN1
