Post Body

I have opnsense running in proxmox and I'm looking into either creating HA, or have both running at once w/CARP to create failover. However, I'm noticing that when one NUC is given an IP by my ISP's DHCP, the other one won't get one, and will instead get one from my internal LAN.

How do I avoid this happening? Is this an issue with my ISP only wanting to give me one IP at a time, and if so, how can I make my opnsense instances 'share' the IP? I don't think the local DHCP is somehow getting there first and then stops looking for my ISP's.
