Conversion from Bridged to Routed on Hetzner

[usmannasir]

Hi,

My bridged config


This is bridged networking on hetzner proxmox server

root@rescue /mnt2/etc/network # cat interfacesback

# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

source /etc/network/interfaces.d/*

my routed config

auto lo
iface lo inet loopback

iface lo inet6 loopback

auto enp98s0f0
iface enp98s0f0 inet static
    address 95.216.72.86/32         # Main IP
    gateway 95.216.72.65            # Gateway for Main IP

iface enp98s0f0 inet6 static
    address 2a01:4f9:2b:8ac::2/64  # IPv6 address
    netmask 64
    gateway fe80::1

# Routed Bridge Interface
auto vmbr0
iface vmbr0 inet static
    address 95.216.72.86/32         # Main IP (same as enp98s0f0)
    bridge-ports none
    bridge-stp off
    bridge-fd 0
    up ip route add 135.181.52.232/32 dev vmbr0   # Route for the foreign IP
    up ip route add 95.216.72.64/26 via 95.216.72.65 dev vmbr0 # Add route for the subnet

iface vmbr0 inet6 static
    address 2a01:4f9:2b:8ac::2/64  # IPv6 address
    netmask 64
    up ip -6 route add 2a01:4f9:2b:8ac::/64 dev vmbr0

i've one single fail over ip and one subnet

Subnet:	135.181.52.232
Netmask:	255.255.255.248
Broadcast:	135.181.52.239

my bridged config works, but as soon as i configure routed, network stops working
