please post your proxmox /etc/network/interfaces && your vm guest os ip configurationI tried the add pointopoint again and it worked for the main ip
I have a second IP in the Range (+1 higher than the Main ip)
This IP is bound to the MAC of a VM
As soon as I added pointopoint and changed the mask to /32 for the main ip in the bridge, the VM was not reachable anymore
auto lo
iface lo inet loopback
iface enp9s0 inet manual
auto vmbr0
iface vmbr0 inet static
address 144.76.91.x/27
gateway 144.76.91.161
# pointopoint 144.76.91.161
bridge-ports enp9s0
bridge-stp off
bridge-fd 1
bridge_hello 2
bridge_maxage 12
auto vmbr1
iface vmbr1 inet manual
bridge-ports none
bridge-stp off
bridge-fd 0
so, are you sure that you need point to point ?here the current
Code:auto lo iface lo inet loopback iface enp9s0 inet manual auto vmbr0 iface vmbr0 inet static address 144.76.91.x/27 gateway 144.76.91.161 # pointopoint 144.76.91.161 bridge-ports enp9s0 bridge-stp off bridge-fd 1 bridge_hello 2 bridge_maxage 12 auto vmbr1 iface vmbr1 inet manual bridge-ports none bridge-stp off bridge-fd 0
the change I tried ... uncomment the point to point and changed /27 to /32
The VM is connected vmbr0 - it is opnsense firewall
With WAN port 144.76.91.(x+1)/27
Which words fine in this config above
