Upload slow when using openwrt router

Upload slow when using openwrt router connect to zte mc801a 5g router

My network a zte mc801a 5g modem , the bandwidth is about 500mbps dl/100 mbps ul

When using zte router itself or using a asus rog-ax6000 as dhcp , everything is alright

But when using an verizon cr1000a openwrt, the upload speed is limited to only 25-30mbps

Tried to play with mac address clone, port forward from zte , bridge mode passing the public ip to openwrt , none of them help with the upload speed

Also tried with on/off packet steering and software offload , none of them help also

Anyone is facing similar issue and solved before?

Wi-Fi o Ethernet ?

do you want to do double nat or similar ?

Please connect to your OpenWrt device Verizon CR1000a using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

yes, still on double nat
but tried once on bridge mode, from zte-mc801a passing ip direct to cr1000a, the upload is still limited

I don't see any problems with your configuration files

you have the possibility to install Iperf3 on the ZTE MC801A, or to test the connection by creating a server (DHCP server + Iperf3 server) <--> (wan) Verizon CR1000a (LAN) <--> PC client (iperf3 client) to understand if does the speed detected depend on the internet connection or on any malfunctions?

tried disconnecting mc801a and connect to another modem in different site,everythings alright , seems the limiter happen between zte mc801a lan and cr1000a wan, some kind of negotiation problem or limiter happens

will try another one cr1000a with default firmware to debug with
