Hook script not working (libvirt+qemu+virt-manager)?

Question

Virtualization

The main OS Centos 6.8 (111.11.11.1), inside the Windows Server virtual machine (192.168.122.40)
I did it according to this principle: I
created a file in /etc/libvirt/hooks/qemu

spoiler

#!/bin/bash
# used some from advanced script to have multiple ports: use an equal number of guest and host ports

# Update the following variables to fit your setup
Guest_name=vm5
Guest_ipaddr=192.168.122.40
Host_ipaddr=111.11.11.1
Host_port=(  '8041' '8042' )
Guest_port=( '80' '443' )

length=$(( ${#Host_port[@]} - 1 ))
if [ "${1}" = "${Guest_name}" ]; then
   if [ "${2}" = "stopped" ] || [ "${2}" = "reconnect" ]; then
     for i in `seq 0 $length`; do
        iptables -t nat -D PREROUTING -d ${Host_ipaddr} -p tcp --dport ${Host_port[$i]} -j DNAT --to ${Guest_ipaddr}:${Guest_port[$i]}
        iptables -D FORWARD -d ${Guest_ipaddr}/32 -p tcp -m state --state NEW -m tcp --dport ${Guest_port[$i]} -j ACCEPT
     done
   fi
   if [ "${2}" = "start" ] || [ "${2}" = "reconnect" ]; then
     for i in `seq 0 $length`; do
        iptables -t nat -A PREROUTING -d ${Host_ipaddr} -p tcp --dport ${Host_port[$i]} -j DNAT --to ${Guest_ipaddr}:${Guest_port[$i]}
        iptables -I FORWARD -d ${Guest_ipaddr}/32 -p tcp -m state --state NEW -m tcp --dport ${Guest_port[$i]} -j ACCEPT
     done
   fi
fi

Next
service libvirtd restart
and such an error

Or is it easier to create a bridge
