Internet access from Host-only network

Question

Initial situation

I need to share internet between two VMWare images that work within host-only network, where one host would be a server and another a client.

I'm working with VMWare Workstation and have two kinds of Virtual Networks:

1. VMnet4:
   • Type: Host-only
   • Subnet IP: 192.168.237.0/24
2. VMnet8:
   • Type: NAT
   • Subnet IP: 192.168.56.0/24
   • Gateway IP: 192.168.56.1
3. PC's IP in a context of VMNet8 network is 192.168.56.5

With such Virtual Networks I have two hosts with following configurations:

1. KaliLinux 2019.3:

ip addr

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:b5:bd:69 brd ff:ff:ff:ff:ff:ff
    inet 192.168.56.10/24 brd 192.168.56.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:feb5:bd69/64 scope link 
       valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:b5:bd:73 brd ff:ff:ff:ff:ff:ff
    inet 192.168.237.1/24 brd 192.168.237.255 scope global eth1
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:feb5:bd73/64 scope link 
       valid_lft forever preferred_lft forever

ip route

default via 192.168.56.1 dev eth0 onlink 
192.168.56.0/24 dev eth0 proto kernel scope link src 192.168.56.10 
192.168.237.0/24 dev eth1 proto kernel scope link src 192.168.237.1 

iptables rules

#!/bin/bash

outer_interface=eth0
inner_interface=eth1
inner_subnet=192.168.237.0/24
internet_ip=192.168.56.10

sudo iptables -F
sudo iptables -t nat -F
sudo iptables -t mangle -F
sudo iptables -X

sudo iptables -A FORWARD -i $inner_interface -o $outer_interface -s $inner_subnet -j ACCEPT
sudo iptables -A FORWARD -i $outer_interface -o $inner_interface -d $inner_subnet -j ACCEPT
sudo iptables -P FORWARD DROP

sudo iptables -t nat -A POSTROUTING -s $inner_subnet -o $outer_interface -j SNAT --to-source $internet_ip

echo 1 > /proc/sys/net/ipv4/ip_forward

2. Ubuntu Desktop 18.04 - as a client

ip addr
