ltsp 2 Nic still not working (Mint and Debian)

Hello
I am trying to install LTSP in Mint 19 and after Debian 9. The client side
up but not connect internet. I go show my steps on Debian

1 - install packages

sudo apt-get install ldm ldm-server ldm-themes ltsp-client ltsp-client-core
ltsp-docs ltsp-server ltsp-server-standalone ltspfs ltspfsd ltspfsd-core

2 - configure second nic to LTSP
etc/network/interfaces

# 2 NIC
auto enp1s10
iface enp1s10 inet static
address 192.168.67.1
netmask 255.255.255.0

3 - Restart Network Manager:
sudo systemctl restart network-manager

4 - Create file default dnsmasq:
sudo ltsp-config dnsmasq

5 - Edit file /etc/dnsmasq.d/ltsp-server-dnsmasq.conf
# dhcp-range=10.1.1.0,proxy (comment here#)
#port=0
change
port=o

6 - Edit file: /etc/ltsp/update-kernels.conf

# Supported booth methods
BOOT_METHODS="NBD AOE NFS"
change to
BOOT_METHODS=NBD

#IPAPPEND=3
change to:
IPAPPEND=3

7- Create the client image:
sudo ltsp-update-image --cleanup /

8 - Create lts.conf file:
sudo ltsp-config lts.conf

9 - In file /var/lib/tftpboot/ltsp/amd64/lts.conf
insert line:
DNS_SERVER=8.8.8.8

10 - Enable IPV4 forward
In file /etc/sysctl.conf
#net.ipv4.ip_forward=1
change to:
net.ipv4.ip_forward=1

11 - Create file inside /etc/network/if-up.d and insert line:
#!/bin/sh
iptables -t nat -A POSTROUTING -o eno1 -j MASQUERADE   ????
Internet NIC or LTSP NIC?

Here stiil not tested
Do Need I Enable NAT or not?
sudo iptables --table nat --append POSTROUTING --jump MASQUERADE --source
(IP LTSP NIC)

and last Do Need I permanent  enable NAT?
command:
sudo sh -c 'iptables-save > /etc/ltsp/nat'

LTSP no connect Internet on Debian and Linux Mint but the client side up
