Assigning private IP to a container from host which is connected to a private vSwitch network.

[farbod]

Hello,
I have a Hetzner server with Proxmox installed.
I have connected my host to a vSwitch and assigned a private IP to it.
now i want to assign another IP from that private network to one of my containers.
I have connected 5 Proxmox nodes to this network and they can communicate with no problem.
but i want to my container also be in that private network to communicate with other containers on private network or other nodes.
here is my nodes network configuration;

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

iface lo inet6 loopback

auto enp35s0
iface enp35s0 inet static
        address 65.109.111.229/26
        gateway 65.109.111.193
        post-up echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up echo 1 > /proc/sys/net/ipv4/conf/enp35s0/proxy_arp
        up route add -net 65.109.111.192 netmask 255.255.255.192 gw 65.109.111.193 dev enp35s0
# route 65.109.111.192/26 via 65.109.111.193

iface enp35s0 inet6 static
        address 2a01:4f9:3051:3e22::2/64
        gateway fe80::1

auto enp35s0.4001
iface enp35s0.4001 inet static
        address 192.168.100.4/24
        mtu 1400

auto vmbr1
iface vmbr1 inet static
        address 65.109.111.229/26
        bridge-ports none
        bridge-stp off
        bridge-fd 0
        bridge_maxwait 0
# Our Host will be the Gateway for all VM's
# Some basic bridge configuration

  up route add -host 135.181.175.0 dev vmbr1
  up route add -host 135.181.175.1 dev vmbr1
  up route add -host 135.181.175.2 dev vmbr1
  up route add -host 135.181.175.3 dev vmbr1
  up route add -host 135.181.175.4 dev vmbr1
  up route add -host 135.181.175.5 dev vmbr1
  up route add -host 135.181.175.6 dev vmbr1
  up route add -host 135.181.175.7 dev vmbr1

My host uses a vswitch with vlanID 4001 and mtu 1400.
