Getting Started#
Applicable to the CatWrt series, as well as LEDE, not applicable to the OpenWrt mainline LuCI 18.06+. I think this method is relatively standard.
There are several ways to install CatWrt on the x86_64 platform:
- Fresh installation (PE)
- System upgrade (overwriting partitions on the existing system)
- Container (LXC, Docker)
Here we use the PE method, which is suitable for most people, including virtual machine users. This also includes the Wireless router series for users with wireless routers. Please skip if not applicable.
However, virtual machines can directly import the hard disk. Importing the VMDK file directly is prone to corruption when power is cut off. VMware users are recommended to choose the PE installation method. PVE, UNRAID, and others can directly import virtual hard disk files.
Installation#
Fresh Installation (x86)#
Tools needed:
- Brain
- USB drive
- Keyboard and mouse
- Ventoy Download Source: Github Ventoy
- WEPE Download Source: Shandong University
- UltraISO Download Source: UltraISO
- IMG Writer Download Source: roadkil.net
- CatWrt Blog
Here I will demonstrate it briefly. First, you need to install UltraISO. There are no special considerations here, just click "Next" to proceed.
Next, extract Ventoy and open Ventoy2Disk.exe. Select your USB drive for installation. Please note that your USB drive will be formatted, so make sure to backup your data.
Open the WEPE toolbox and select "Other installation methods - Generate bootable ISO" in the lower right corner.
Open the generated WEPE ISO file using UltraISO. If a prompt appears asking for a subscription, select "Continue Trial".
Then, put the IMG Writer and CatWrt img image into the ISO file. Here, I recommend using EFI firmware for new machines. When everything is processed correctly, the file structure should look like this.
| WEPE.ISO
.
├── EFI
├── WEPE
├── BOOTMGR
├── DiskImage_1_6_WinAll.exe
├── CatWrt.v23.8.x86_64-squashfs-combined-efi.img
Insert the USB drive with the keyboard and mouse connected to the machine, and then power on the machine. Select to boot from the USB drive and choose the WEPE option in the Ventoy interface. There is nothing specific to note here.
After entering the desktop, open "This PC" (File Explorer) and find the DVD drive labeled "WEPE Toolbox". Open the IMG Writer tool DiskImage_1_6_WinAll.exe and select your hard drive in "Write Image to" as Physical Disk 0(223.57 GB). Please note that selecting a partition here is incorrect.
Then, in the "Source File" section, click "Browse" to find the IMG image, and click "Start" to confirm and start writing the image to the disk. After the writing is completed, restart the system and remove the USB drive.
Regarding EFI firmware, if you encounter issues with booting, it is recommended to contact the industrial control machine manufacturer to inquire about how to enable UEFI and disable secure boot.
UBOOT (Wireless)#
For the Redmi AX6000 router, plug it in and press and hold for 15 seconds to access UBOOT at http://192.168.31.1.
For the TP-Link XDR 4288/6086/6088 router, plug it in and press and hold for 5 seconds to access UBOOT at http://192.168.1.1.
Select the image in the preview file and click "Update" to proceed.
Changing Network Segment (x86)#
If the network segment of CatWrt, which is 192.168.1.4/24, is different from your network architecture, you need to change it. In general, there is no need to change it~
Since it is not initialized yet, we will operate in the terminal. Enter nano /etc/config/network to start editing.
Find the option ipaddr '192.168.1.4' in the config interface 'lan' section and replace the IP address inside the single quotes. Be sure not to delete any punctuation marks!
After editing, press [ctrl]+[O] and you will see "File Name to Write: /etc/config/network". Press Enter to save. Then press [ctrl]+[X] to exit the nano editor.
Enter reboot to restart the system and apply the configuration changes.
Initialization#
In the following operations, the shortcut link is set to 192.168.1.4 by default. If you have modified the network segment, please manually enter it.
Change Password#
The default password is password. If your gateway needs to connect to the Internet and you have public network conditions (IPv4/v6), it is easy to be exposed to the public network and become a member of a zombie network. Therefore, we need to change our password.
After logging into the background, go to System-Administration and find the Host Password section. Enter your password and confirm it, then save it.
Lan (DHCP)#
Here is an example for a four-port industrial control machine. By default, there are only eth0 (lan) and eth1 (wan, wan6). You can directly refer to the following configuration.
If it is a virtual machine or a dual-port industrial control machine, you don't need to do anything here. Just leave it as it is, or you can swap the ports if necessary.
- General Configuration - Basic Settings

PPPoE#
By default, the connection is through DHCP. If you need to dial-up for internet access, click on the Protocol Name section and select PPPoE. Then enter your broadband account and password. For specific details, you can contact your ISP customer service or ISP installer.
Click Save and proceed to the next step without applying.

UPnP#
It is recommended to enable UPnP to improve P2P efficiency. However, using UPnP may cause streaming media software and domestic downloaders (such as Thunder and Baidu Cloud) to use your broadband for commercial purposes.
