DNAT IPv6 outside IPv4 inside, packet dropped

Bart van Kampen
Hi all,

I'm trying to reach my webserver, wich is behind a UTM 9.308. 
The WAN side of the UTM is IPv6, and the LAN side is IPv4. 

I've added a DNAT rule, to change the destination that reaches my UTM on port 80, to the internal network.

I've also added an Any to Any allow rule in the Firewall (for excluding the firewall from this problem). But I still get an Default Drop. 

When I search on the internet, I've found some website that tells me that my DNAT rule isn't good. But I don't really see the problem, can you guys help me out?

See the attached image for the UTM settings / logs. 

Thanks (again),
Bart

Network:
Host (::5)  WAN UTM (::11)  LAN UTM (192.168.22.1)   Server (192.168.22.12)
