[SpitzAx] Is it possible to have MultiDMZ via MultiWAN in this router?

For example,1 DMZ LAN IP address for 5G WAN IP address  
then another 1 DMZ LAN IP address for Ethernet based WAN IP address  
then another 1 DMZ LAN IP address for 4G/Tethering? etc?

One DMZ rule applies to all WAN zones. This means that you can access the internal server using the IP address of the 5G WAN, Ethernet-based WAN, or 4G/Tethering IP.

However, this is limited to Ethernet-based WAN when VPN client is on, for implementation reasons.

Then, the best solution would be to buy 3 separate routers for separate WAN & DMZ 🤔

I’m not familiar with the built in firewall.  
I’ve SNAT and DNAT rules for this in other routers.
