Hetzner Proxmox host + pfSense vm networking

[Fatih90]

Hello all i cant seem to make this work as i try to follow the guide here https://dannyda.com/2020/06/09/how-...-ve-6-2-pve-easily-works-for-vmware-esxi-too/

i have a dedicated server with main ip

178.**.**.75

and ordered a second ip for pfsense

178.**.**.79

also ordered a subnet /29 for my vms to get it from pfsense

88.**.***.40

to

88.**.***.47

now my interfaces file is this

auto lo
iface lo inet loopback

iface lo inet6 loopback

auto enp3s0
iface enp3s0 inet static
    address 178.**.**.75/32 # Hetzner Main IP
    gateway 178.**.**.65
    pointopoint 178.**.**.65

iface enp3s0 inet6 static
    address 2a01:4f8:120:82f8::1/128
    gateway fe80::1
    up sysctl -p

auto vmbr0
iface vmbr0 inet static
    address 178.**.**.75/32 Hetzner Main IP
    bridge-ports none
    bridge-stp off
    bridge-fd 0
    bridge-maxwait 0
        #Second IP for pfsense
    up ip route add 178.**.**.79/32 dev vmbr0
    # subnet
    up ip route add 88.**.***.40/32 dev vmbr0
    up ip route add 88.**.***.41/32 dev vmbr0
    up ip route add 88.**.***.42/32 dev vmbr0
    up ip route add 88.**.***.43/32 dev vmbr0
    up ip route add 88.**.***.44/32 dev vmbr0
    up ip route add 88.**.***.45/32 dev vmbr0
    up ip route add 88.**.***.46/32 dev vmbr0
    up ip route add 88.**.***.47/32 dev vmbr0
    # subnet
    
iface vmbr0 inet6 static
    address 2a01:4f8:120:82f8::2/64

auto vmbr1
iface vmbr1 inet manual
    bridge-ports none
    bridge-stp off
    bridge-fd 0

the problem is when i configure my LAN using second ip i cant ping the host but if i use any of the usable ips from the subnet i can ping it and can access the pfsense dashboard

can anyone help me out pls i am going crazy with this

Hi!

Have you already compared this to the Hetzner Wiki article about Proxmox VE networking, and also with the Proxmox VE documentation about networking options?
