Can't Access WebGui without running /sbin/modprobe iptable_mangle

[CoffeeLovingDad]

Every time I restart my server and start Qbittorrent (using VPN) in Docker; I then have to run /sbin/modprobe iptable_mangle and then restart the Qbittorrent Docker container then I'm able to access the Webgui successfully.

Were you ever able to find a solution for this? I'm running into the same issue.

Yes I actually resolved this using ChatGPT.

It sounds like you're running into a problem where you need to load a kernel module (iptable_mangle) each time you restart Docker to access the web GUI of qBittorrent. This can be inconvenient, so here's how you might address the issue:

1. Automate Module Loading

You can automate the loading of the iptable_mangle module at boot time. Here’s how you can do that:

For Systemd-Based Systems (e.g., Ubuntu 16.04+):

1. Create a systemd service file:

   Create a new service file, for example /etc/systemd/system/load-iptable-mangle.service, and add the following content:

   [Unit]
   Description=Load iptable_mangle Module
   After=network.target
   
   [Service]
   Type=oneshot
   ExecStart=/sbin/modprobe iptable_mangle
   RemainAfterExit=true
   
   [Install]
   WantedBy=multi-user.target

2. Enable and start the service:

   sudo systemctl daemon-reload
   sudo systemctl enable load-iptable-mangle.service
   sudo systemctl start load-iptable-mangle.service

This will ensure that the iptable_mangle module is loaded automatically at boot.

2. Ensure Module Persistence Across Reboots

Sometimes, the module might not persist across reboots. To ensure it's always loaded:

1. Edit the modules configuration file:

   Add iptable_mangle to the /etc/modules file. Open the file with your preferred text editor:

   sudo nano /etc/modules

   Add iptable_mangle on a new line and save the file.

   iptable_mangle

   This will ensure the module is loaded at boot.

Let me know if you need further help, that should point you in the right direction.

Thanks for the quick reply. Probably should have asked chatgpt but I completely forget that was an option lol. Appreciate the help, ill get this implemented tonight on my server.

No problem, was something that'd been bugging me for years and I hadn't taken the time to resolve it then resolved it right after posting the question here last month.

Good luck.
