Palo Alto Error – Error Message When Adding a New Tunnel Interface


I am an intermediate, not professional network admin for my own small business. I am attempting to add a new tunnel interface for a new VPN branch. I'm using the same config I have implements many times before – this will be my 4th branch. However I'm running into this error message I can't resolve myself. Here is the text from the commit error…

"In virtual-router default: address on interface vlan.2 is duplicate with address on interface ethernet1/1.(Module: routed)
Commit failed"

Which seems to have nothing to do with the new tunnel I am adding, which will be a network on Ethernet 1/1 is my wan connection, which is gets a dhcp ip address from my isp, and has no interface ip address specified. My vlan serves addresses on network

In my own troubleshooting, it seems that if I make any change at all to my virtual router config, commits will fail with this error.

I'm lost, I've searched my config and cannot find what it is referring too. Any ideas what's up?

I really appreciate the assistance!

Wanted to update with how I resolved this. Basically something apparently got corrupted in the config files. The behavior started when I was trying to add a new tunnel interface, but initially would disappear when I reverted to one of my saved configs. After a while even this action would not resolve the error (same one noted above). So - I reverted to factory! Needless to say that is less than ideal, I'm very surprised to have this type of issue with this box. Once I did so I was able to import my saved configuration file and add the tunnel interface with no errors.
