Route Tailscale IP/Traffic to Proxmox pfSense VM

SUPPORT QUESTIONS

Hello,
i need your help and hope you can give me the right config. I tried and search a lot, but nothing works.
I have a Proxmox host and inside a pfSense-VM with Tailscale. How can i route traffic for Tailscale network (specific Tailscale IP) from host to my pfSense and send it to Tailscale Network.
Example: ping from Proxmox-Host (CLI)—>[pfSense/Tailscale]—> my Phone(Tailscale IP).
From pfSense <—> Phone, works

My Setup and what i need:

network

My default-Config:
/etc/network/interfaces

auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
        address 116.XX.XXX.80/32
        gateway 116.XX.XXX.65
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0
        post-up echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up iptables -t nat -A PREROUTING -i vmbr0 -p tcp -m multiport ! --dport 22,8006,60000:60050 -j DNAT --to 10.0.0.2

i think on pfsense tailscale, you need to advertise your subnet routes.
e.g: tailscale up --advertise-routes=192.168.1.0/24,10.0.0.0/30.

than traceroute from your proxmox host to one of your tailscale clients and see if the proxmox host is going over the pfsense. otherwise you need to manually configure the routing for the tailscale network on your proxmox host.

the simple solution would be to install tailscale directly on the proxmox host.
