Since I have experienced this issue several times before and I can never remember the commands needed to figure out what is wrong, I figured I would write a quick post. The issue is upon reboot of a Vyatta firewall you receive a ‘configure failed!’ error message. The exact error message depends on which features you have enabled on your device, but one example is:
Starting Vyatta router: migrate r1-system firewall configure failed!
So how do you check what changed / what is causing the issue?
Simply log in and run the following commands:
That’s it! You should now see exactly what is causing the problem and then be able to fix the issue.
