Comment on Going nuts with networking of VMs on Proxmox (SOLVED)
trilobite@lemmy.ml 6 days agoJust to be clear, this is what is in the ARP table on pfSense: Image and this is what is in the DHCP lease table in pfSense. Image What I’ve concluded is that the DHCP sees the VM is online, it probably offered the 91 IP, and just shows it online. The ARP table is showing what the actual assigned IP is (106) and SSH login attempts confirm this. There is no 106 entry in the DHCP table. I would ignore the VM2 element of the equation i described above for now. I added just to describe the conflict that arose when I switched it on. I woudl also say that VM1 was backed up on another Proxmox server I had runnina and then restore it on this new Proxmox server I have with a bigger NVMe.

Yeah this still sounds very much like what I had happen. pfSense tries really hard to hang on to that old random dhcp lease sometimes.
Don’t worry about ARP- that just shows what currently exists.
You might try turn off the vm, delete the static mapping, then delete the DHCP lease in status - dhcp leases, then add the static mapping again and turn the vm back on.
Also on pfSense check /var/dhcpd/var/db/dhcpd.leases . Chances are your VM is in there. Turn off VM, stop DHCP service on pfSense, delete lease from that file, restart DHCP service, check static mapping, turn on VM.
Let me know if that works…

a) turned off VM b) deleted the static mapping and recreated c) change the MAC on the VM and then the same MAC on pfSense d) checked /var/dhcpd/var/db/dhcpd.leases and there is no sign of any 192.168.20.XX lower than 20.110 (from 110 I leave the space availble for occasional wifi access of devices not in my home) e) Rebooted pfSense
absolutely the same problem again :-(

Hmm Are you wedded to that particular Mac address? If not, shut down the VM, delete the virtual Network card, then make a new virtual Network card. Copy paste the Mac of that new card into pfsense with the static mapping, and fire up the VM. See what happens.
If that doesn’t work, I remember something it was possible for proxmox to do some kind of routed Network system. To investigate that, delete all static mappings, fire up the VM, and just look at what Mac address it shows getting the DHCP lease. Is it the one that shows as being assigned to the VM?
