Hey All,

I've been running into an issue after upgrading to 6.7.2 . Where br2 becomes the default route.

The issue with this is that I don't have anything plugged into br2. I am currently only using br0, because it is my 10G link. br1, and br2 are only 1G links. So, I really don't want to use them. 

 

I was able to fix this by modifying the route table manually. However, if I modify it manually after a reboot it reverts right back. 

 

The weird thing is also if I downgrade back to 6.6.7 I don't have this issue. 

 

So, my primary question is what is the best option for making the br0 route persistent across reboots?

Post the content of the file "network.cfg" in the /config folder on your USB stick.

Here you go.

 

Like I said, the most baffling thing about it. Is that it worked just fine with the previous version of unraid when I downgraded. As well as naturally working before the upgrade.

Ok, so I sort of figured it out. If I turn off bridging on eth1, and eth2 then leave it on, on eth0, then bridge them all together it seems to work correctly.

If someone has a better way to do this than bridging ports that aren't even plugged in I'm all ears. However, it does look like doing this does seem to persist after reboot.
