Trouble With Bridging

[aiden21c]

Hi! Just wondering if I could get a hand with my new TrueNas Scale install that I am deploying as I seem to have run into a hiccup or two. I set up a new TrueNas scale install and after installing my first VM onto it (Kubuntu) I found that the VM could not see the host system in the network, even though it had full access to the entire LAN. After doing some research this seemed to be a common occurance for TrueNas Scale, and the solution was to create a network bridge, assign a static IP to it, and the assign the NIC on the host system as a member of the bridge.

I did this and everything appears to be working fine, however it now seems that anything I install within dockers/VMs inside TrueNas scale is npt acting as expected. My main issue is with my Plex install (inside a docker) as if I can fix that then I believe I will have a solution for everything. After installing plex, it is appearing that it has major issues being accessed outside of my local network. On the local network I can use the IP of the host system at the given port 32400 to access plex, however Plex is not directly accessible outside my network.

I believe this is because Plex has been assigned an IP by the network bridge of the host and the router doesnt know about this virtual network so it cannot route traffic to it. My solution is to set up a static route from the 192.168.0.1/24 network (my router's LAN) to the 172.16.0.1/24 network which I believe to be the LAN that the bridge is assigning addresses from.

Is my approach correct? Also is there any way from the terminal of the host nas that I would be able to explicitly check what the IP address range the bridge is assigning to my applications. the 'ip a' command gives me alot of info but it is very hard to decipher.

Code:

Hello,

I think I am in the same situations as you.

I have setup a bridge in the TrueNas network settings so that my VMs and communicate with the host. Now my Plex server will not talk to the web it seems, I am using the TrueNas App version of Plex, if that makes a difference.

Just asking to see if you have found a solution to this yet?

All the best,
Jack
