Strict Mode was actually introduced a long time ago specifically for Destiny. It's been a long time and not many customers seem to play it anymore so I can't be certain if it's still needed at the moment, try with and if you run into any trouble disable it and see if that is better.

NAT Type 1 = Open NAT connected direct to a modem
NAT Type 2 = Open NAT connected to a router
So it is impossible to get NAT Type 1 through the router, it's also unnecessary as you'll already be open

I reset router I try different Web Google and Edge and fire fox give me same thing 
It say dumaOS is unable to complete the ping optimizer  process  due to external  circumstances 

You wouldn't be able to use your max speeds, the ports on the R3 are 1Gbps ports

You need to do the DMZ step I mentioned, that will fix the double NAT

Ah understood, I can see you've set the router LAN IP to 192.168.77.2 instead of 77.1 is there a reason for that? Usually router LAN IPs always end in .1 so devices use the rest of the IPs.
Put your Fritzbox back and have that use PPPoE, then connect the R2 to it (remove PPPoE from the R2) and copy the WAN IP from the R2 System Information page and put that in the fritz DMZ then check the speeds through the R2.
