Seems I have had a similar issue as in a post from :

I just upgraded to 6.7.0 rc7 and I lost internet access from unraid. The rest of my network is fine, I can access the GUI and I can ping my router from unraid. I can't ping 8.8.8.8 or any other internet address and some unraid functionality is lost such as docker updates (access to GitHub). A downgrade to 6.6.7 brings it all back!

 

Any ideas?

 

in this thread he found that in his network.cfg he had a duplication with the settings, and bonienl had him go in and edit the file to remove the nic that was not supposed to be there.

 

I believe I have a similar situation, where I have a nic listed that is not presented (eth1), and I can remove that entry and see what happens.  But in that post bonienl also said to change the sysnics=   What is that parameter setting?  I am sure I am going to have to adjust it.  I have included a copy of my network.cfg below:

Something which has worked in the past is to rename  network.cfg   is something like  network.cfg.old   and reboot.   This will force a rebuild of the file and has fixed networking issues in the past after an upgrade. 

 

I would suggest that you do a backup of the Flash Drive before you start.   Main    >>>   Boot Device    Click on the 'Flash' under the "DEVICE" column.  Look for the FLASH BACKUP button under the "Flash Device Settings" tab/section.  (Always a good idea to have a backup.  That way, you will never need it! 😈 )

Remove the gateway setting (10.71.72.1) from the onboard interface, this is causing routing loops.

 

Also the assignment of the secondary interface 10.71.72.24/24 overlaps with the assignment of the onboard interface 10.71.72.6/29.

You need to make this non-overlapping.

I implemented the changes suggested by bonienl, as they were the least invasive to start with, and removing the gateway 10.71.72.1 resolved the internet connectivity issue.

As a second I also changed subnet of the secondary interface so things were not overlapping.

 

Thanks for the quick feedback.
