SOLVED Two OpenVPN Jails. One for remote access, another for qbittorrent. Conflicts with tun* and ifconfig

[nvasile]

Greetings All,

This is my first post, and I apologize if there aren't enough details, I'm not really sure what I should post in terms of configuration/specs, but I'm using FreeNAS-11.3-U4.1

The Problem:
Currently I have three jails: qBittorrent (plugin), OpenVPN, and Plex (plugin). The OpenVPN jail is for remote access to my LAN/SMB share. The qBittorrent jail is for torrenting (of course) and I want to connect to the NordVPN service via OpenVPN to hide my IP and to some extent my traffic from my ISP while torrenting. But if I have my OpenVPN jail running, my qbittorrent can't connect via NordVPN. If I have my qBittorrent jail running my remote OpenVPN connection cant reach any devices on my LAN.
In short: The two jails jails only work as intended when the other is stopped

To my understanding both connections are trying to use the same interface, or dont have permissions to make another interface? (Really not sure)

Here is the output of cat /var/log/messages in the qBittorrent jail while my OpenVPN jail is running and blocking(?) it:

and the output of ls -l /dev/tun* (same in or out of the qbit jail)

crw------- 1 uucp dialer 0x114 Sep 12 12:46 /dev/tun0
crw------- 1 uucp dialer 0x115 Sep 12 12:40 /dev/tun1

I setup the OpenVPN jail with this script from Bibi40k and the qBittorrent jail is the official plugin with the openvpn package installed and the ovpn file provided from NordVPN. I'm not very networking-savvy, but I'm comfortable using the cli, so please let me know if there is any configuration/files and their directories that would help debug this.

Thanks,
Nick

SOLVED! All I had to do was:

1. Stop the qbittorrent jail
2. Commenting out the last 3 lines from the file: OpenVPN-on-FreeNAS-in-iocage/blob/master/src/server/ipfw.rules
   source file is: https://github.com/Bibi40k/OpenVPN-on-FreeNAS-in-iocage/blob/master/src/server/ipfw.rules
3. start up qbittorrent jail and select tun1

The fix works and I can vpn in and use my torrenting software at the same time!

Oops, forgot:
2.5 clean and install the openvpn jail again so the changes take effect*
