Sync overwrites FHRPGroup assignement
Hi,
i got netbox 2.4.2 and netbox-sync 1.8.0 runnig. It's really synching great. Only two virutal firewalls with CARP addresses assigned as FHRP-groups got an issue. The assignment to the FHRP groups gets reassigned to one of the vNICs of them, although there is a warning the IPs will be skipped cause they are enabled on two VMs.
From the log(DEBUG3) it looks like this:
2025-03-12 07:23:20,727 - DEBUG2: Found existing NetBox IP address object: 192.168.205.1/27

Is there any way to keep netbox-sync from changing these assignements?

Hi,
Looking at it, I would suggest following: If the found IP is a FHRPgroup assigned, then it should be possible to assign this IP to multiple interfaces. In this case NetBox should not complain about it. Would of course on first synchronizations, where this info is not available, result in the same error. Then assigning this address to a vhrp group should stop the error messages. Will test this behavior.
Hi @bb-Ricardo , I tried different ways with FHRPgroup assigend IP / Interfaces, but netbox-sync always pulls the IP back to the VM-Interface. May I assist in debuging? I'm not yet fit in python to check the code, but I may try to learn it. Cheers Io
Sorry, just wanted to let you know that I have been busy lately and therefore had not much time looking into this issue. It's still on my todo list.
