I am recently experiencing some problems configuring a vpn server on my gl.inet opal device
I use my device in ethernet mode
and in the wan port of my opal device i connected my isp's router brand ZTE
of course i configured in my isp's router port forwaring with port 51820 to use wireguard
obviously the main router and the gl.inet device have different ip classes
the gateway on my isp's router is 192.168.0.1/24 and opal in the network takes ip address 192.168.0.8, then internally on the gl.inet device i have class 192.168.8.1/24
the open port in the isp router is on address 192.168.0.8
i have subsequently configured wireguard server in a regular way as also shown in the instructions and enabled the Allow remote LAN access feature
but still the vpn doesn't work in any way
in the wireguard logs I don't see anything strange

I think it's a problem of interface configuration or firewall
Is it configured correctly ?
At the configuration level on luci I haven't touched any other firewall rules so I don't know
Has anyone encountered the following problem and can give me advice on how to solve it? I even tried configuring wg on a different port for fear that my isp's router would block the following port but still nothing
i ask for your help because i dont know how to proceed anymore if needed i can provide more detailed troubleshooting details
client configuration

thank you for helping me
