NAT64 (jool) is not working

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello!

I've setup official OpenWRT (OpenWrt 23.05.0) on my MI Router 4C; then installed and configured NAT64 (jool) using docs from https://openwrt.org/docs/guide-user/network/ipv6/nat64 (this docs are out-of-date, so I found new here Update NAT64 jool instructions) .

Then attached my windows 10 laptop by ethernet cable to the router (I disabled IPv4 in network settings on windows 10) and tried to execute in my console:

ping 8.8.8.8
ping 64:ff9b::8.8.8.8

First ping command executed sucessfully. Second one printed timeouts.

Could you please help me with NAT64? How can I debug it? May be I need to configure something else?

Is that enabled on Windows?

How about:

ping 64:ff9b::808:808

Does a local IP work?

IPv6 device is windows 10. My ipconfig output from this device:

ping 64:ff9b::808:808

Same thing:

C:\Users\lenovo>ping 64:ff9b::808:808

Does a local IP work?

I can ping my openwrt from windows 10:

C:\Users\lenovo>ping fe80::46df:65ff:fe6e:f0b8

Hey guys.
I have a question, I don't know if you can help me, I configured Jool correctly here, on my cell phone my computer goes to the website that is wm ipv4 using ipv6, but my game call of duty warzone it opens but at a certain point it stops , when I put the IP back on the router 192.168.1.1/24 on lan6 where all my Jool configuration is, my game starts working normally again. Reporting that some games work without attaching the IP, but COD does not enter. Could someone tell me why this happens. Could someone explain to me where I might be going wrong?
