I have used this guide to install OpenWrt on my Raspberry Pi 4 behind my ISP router, along with some help from the community.
It installed successfully and I was able to connect to the UI, but I cannot connect to any other outside website or server. It just stops responding.
How can I fix and diagnose this issue?

your eth1 ( wan ) is not plugged in
I plugged in my switch to the Ethernet port of the Pi, and I plugged the Pi to a LAN port of my ISP router using the Pi's USB port using a USB-Ethernet dongle. I then configured the Pi accordingly, set up DMZ on my ISP router to the Pi, and disabled DHCP and Wi-Fi on the ISP router. Is that not how it's supposed to be done?
ifconfig eth1
As you mentioned, yes. But how could I fix it? What is wrong with my setup?
@trendy I need to wait 6 hours before I can reply, for some reason. So I edited this post.
I'm trying to set up my Pi as a router by putting it behind my ISP router, like this:
The "Home Router" is the Pi. The Pi is connected to the switch by the Pi's Ethernet port. The Pi is is also connected to a LAN port of the ISP router using the Pi's USB port using an Ethernet-USB dongle.
You have not explained what are you trying to achieve, so it is hard to answer you.
ifconfig eth1
and post the result here
root@OpenWrt:~# opkg list-installed | grep kmod-usb-net-rtl8152
kmod-usb-net-rtl8152 - 4.19.101-1
root@OpenWrt:~# ifconfig eth1
ifconfig: eth1: error fetching interface information: Device not found
root@OpenWrt:~#
in the LuCi menu -> network -> interfaces, have you tried "add new interfaces" for wan?
What's the output when you run opkg list-installed | grep kmod-usb
I already posted the output for kmod-usb-net-rtl8152, but in case you need the output for all of them:
root@OpenWrt:~# opkg list-installed | grep kmod-usb
kmod-usb-core - 4.19.101-1
kmod-usb-hid - 4.19.101-1
kmod-usb-net - 4.19.101-1
kmod-usb-net-rtl8152 - 4.19.101-1
root@OpenWrt:~#
maybe the error is in the usb to ethernet device... is the device working on pc / laptop? I have similar RTL-8153 USB 3.0 to Gigabit LAN (use the same kmod-usb-net-rtl8512 driver) on my raspberry pi and it's worked so far the last time I've tried.
what's the dmesg output for the usb device?
The dongle lights up when it detects throughput, so I'm pretty sure it's working fine.
dmesg:

root@OpenWrt:~#
had to find out which chipset my adapter is using and install the appropriate kernel module
Similar problem here seems to indicate hardware problem, either
There is no sign of eth1 in the whole dmesg. Chances are it never got detected.
Do an lsusb to verify the chipset of the ethernet adapter.
I guess I spoke too soon, I also encounter similar problem after testing my USB LAN on raspberry pi 4 (May 30 snapshot). After several minutes got error message link down on system logs and "device not ready" on LuCI, gonna try the USB Ethernet on other box first to confirm the error.
Edit : Found the Problem! ,after testing the usb to ethernet LAN in windows 10 laptop, the same problem also occured and after much searching realtek RTL8152 / RTL8153 r (both linux and windows) have problem with USB autosuspend features, usually involved when using USB 3.0 port (since this is gigabit adapter) and having lot activities in the adapter (high download or upload makes adapter dissapearing and reappearing).
The solution given was to disable the USB autosuspend features in windows device manager, since then the problem reduced altough not missing completely. Then I try installing the latest driver from realtek (2020) and problem gone.
Now the problem is how to get the latest driver (realtek has new 2020 linux driver for the chipset) into openwrt... , so maybe OP has similar problem with said USB to LAN Adapter.
