If the FTTH ONT is connected to the WAN port of the router and you didn't make any changes to the configuration regarding the WAN port, then yes, it should act as a NAT router. In this case you should also see records of connections showing in /sys/kernel/debug/mtk_ppe/bind while there is active traffic between WAN and wired LAN.
ONT is connected to the WAN port, the connection is PPPoE IPv4 and IPv6, the only configuration change on wan is the vlan 835 required by my ISP with option device 'wan.835' in network file.
config device
option name 'br-lan'
option type 'bridge'
list ports 'lan1'
list ports 'lan2'
list ports 'lan3'
list ports 'lan4'
config interface 'lan'
option device 'br-lan'
option proto 'static'
option ipaddr '192.168.2.1'
option netmask '255.255.255.0'
option ip6assign '64'
option ip6hint '02'
option ip6ifaceid 'random'
config interface 'wan'
option device 'wan.835'
option proto 'pppoe'
option username 'xxxx'
option password 'xxxx'
option ipv6 '1'
option keepalive '5 5'
option peerdns '0'
list dns '1.1.1.1'
list dns '1.0.0.1'
config interface 'wan6'
option proto 'dhcpv6'
option device '@wan'
option reqaddress 'try'
option reqprefix 'auto'
option peerdns '0'
list dns '2606:4700:4700::1111'
list dns '2606:4700:4700::1001'
I can't understand why but it is allways empty.
Interesting. I never tried PPPoE, my ISP uses IPoE (DHCP).
In /etc/config/firewall you set
option flow_offloading '1'
option flow_offloading_hw '1'
right?
yes, those are my settings
@daniel, you may be interested to know that on my router with 22.03.2, PPPoE and vlan wan.835, now I disabled wed
# cat /etc/modules.d/mt7915e
mt7915e
but left Hardware Flow Offloading enabled in /etc/config/firewall
option flow_offloading '1'
option flow_offloading_hw '1'
in this condition I can see again in /sys/kernel/debug/mtk_ppe/bind the wired offloaded traffic.
Hardware Flow Offloading works very well with wired connections with wed enabled and with wed disabled but seams that with wed enabled there are 2 effects: wed doesn't work and /sys/kernel/debug/mtk_ppe/bind is total empty (wired data disappear) also if practically wired traffic is well offloaded.
Wired speedtest reach in both cases (wed enabled and disabled) 940 Mbps download 475 Mbps upload with CPU below 3% load that is my FTTH nominal speed less overheads.
What is the current recommendation on using wpa2/3 mixed mode (w/ psk sae) wireless for both bands?
I'm currently using wpa2, but I would love to move to 3 with backwards compatibility as an option.
Current Partial Config:
root@OpenWrt:/etc/config# cat /etc/config/wireless
config wifi-device 'radio0'
option type 'mac80211'
option path 'platform/18000000.wmac'
option channel '1'
option band '2g'
option htmode 'HT20'
option country 'US'
option cell_density '0'
option noscan '1'
# option local_pwr_constraint '0'
config wifi-iface 'default_radio0'
option device 'radio0'
option network 'lan'
option mode 'ap'
option ssid 'secret_24Ghz'
option disassoc_low_ack '0'
option encryption 'psk2+ccmp'
option key 'secret'
option wpa_disable_eapol_key_retries '1'
Hey all,
I'm using a Belkin RT3200, and I feel like I'm going insane because regardless of what version of Open WRT I'm flashing, it's stuck in this cycle where after starting up successfully, it reboots into recovery mode and loses all its settings.
I tried 22.03.1 and 22.03.2, and after flashing the image the first time it boots it shows that it is running the version I installed. But within 30 minutes it reboots into recovery and is back to 22.03.0.
I've included my logs from /sys/fs/pstore because I do see a crash/error in them, just not sure what to do with it. Any help would be so appreciated, I just want the router to be stable. 
Seems like the main piece of useful information is: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000034 ?

So to decode this stacktrace we need the matching debugging information. As it is kernel version 5.10.146 it probably belongs to 22.03.2 release, right?
I've manually decoded the stacktrace using kernel-debug.tar.zst and aarch64-openwrt-linux-addr2line from the toolchain. The result doesn't make too much sense, however...

All this involvement of mtk_bmt_nmbm in the very beginning is really weird. You are using the UBI variant, right? Because if so, we can be 100% sure that I have now failed decoding this stack trace, because nmbm isn't used when using the UBI variant of this device.

Thank you for the help! I've never had to debug one of these, so apologies for the missing information.
The last version I had flashed it with was 22.03.2, and I am using the UBI variant, so I'm not sure what is going on either. :\
Where is the other relevant debugging information located? I dug around the system but nothing seemed to be written in /sys/kernel/debug.
To allow reproducing the issue it would be great if you can share your configuration, esp. network, firewall, wed_enable=Y/N, wireless. Of course, remove passwords and sensitive information.
Thank you!

If there is more than one router/access point wpa3 basically requires fast roaming (802.11r) for seamless hand-over, e.g while on a VoWIFI call.
Fast Roaming has a long standing kernel problem (discussed here:
Daemon.err hostapd: nl80211: kernel reports: key addition failed - is this a problem? - #52 by andybjackson ),
Hence I'm still on wpa2.
Once fast roaming is fixed I'll give wpa3 another try.
@umayer, in my recent experience, WPA3 & WPA2 are the same with respect to the nl80211 kernel problem you reference. I have therefore switched to WPA3 for the enhanced security it offers.
It was stable for 4 hours last night, then crashed once I had gone to bed. The odd thing is the error in the /sys/fs/pstore logs looks different.

You configuration looks innocent and almost identical to what I'm using here. No PPPoE, no flow offloading, no VLANs, ...
To know more, maybe try to build OpenWrt from source and enable kernel debug symbols. If you want, I can provide ready-made binaries for you. This will make the stack trace more understandable...

I do not disagree.
I'm using wpa2 because it has one round trip less in key exchange
(see https://wlan1nde.wordpress.com/2018/09/14/wpa3-improving-your-wlan-security/
WPA3-Personal Connection Establishment
The main difference to the WPA2 connection flow chart are the two extra authentication frames.
802.11r would reduce the handshake for transitions between APs to even less than the standard WPA2 key exchange, also for WPA3.
My experience in my environment is that the latency for WPA2 hand over without 802.11r is fast enough for most applications. WPA3 is notably worse for me (e.g. dropping calls on roaming).
Turning on 802.11r would alleviate the WPA3 latency issue, but due to the kernel bug the user experience is worse (for me: loosing WiFi connection every now and then)
Yeah, that's why I've been stumped is it feels like I've set up the bare minimum possible yet it keeps having issues. Almost wondering if I have a defective unit or something at this point.
If providing the read-made binaries isn't too much trouble, that would be very appreciated! Trying to eliminate any possibility for user error on my end as much as I can. 
I can get them installed right away today once I get them from you and will keep an eye on it and report back if (probably when) I get new crash logs.
