How to setup dhcp on ubuntu 18.04?

Question

linux

Hey! guys help me to make it so that the Internet goes from the external local network to the internal network
Given:
- Virtualbox (last)
- Ubuntu 18.04 LTS (client)
- Ubuntu Server 18.04 (dhcp)
dhcp settings:
dhcpd.conf

dhcpd.conf
#
# Sample configuration file for ISC dhcpd
#
# Attention: If /etc/ltsp/dhcpd.conf exists, that will be used as
# configuration file instead of this file.
#
# option definitions common to all supported networks...
#option domain-name "pupyshev";
#option domain-name-servers ns1.example.org, ns2.example.org;
default-lease-time 600;
max-lease-time 7200;
# The ddns-updates-style parameter controls whether or not the server will
# attempt to do a DNS update when a lease is confirmed. We default to the
# behavior of the version 2 packages ('none', since DHCP v2 didn't
# have support for DDNS.)
ddns-update-style none;
# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
#authoritative;
# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
#log facility local7;
# No service will be given on this subnet, but declaring it helps the
# DHCP server to understand the network topology.
#
#subnet 192.168.1.89 netmask 255.255.255.0 {
#}
# This is a very basic subnet declaration.
#subnet 10.254.239.0 netmask 255.255.255.224 {
# range 10.254.239.10 10.254.239.20;
# option routers rtr-239-0-1.example.org, rtr-239-0-2.example.org;
#}
# This declaration allows BOOTP clients to get dynamic addresses,
# which we don't really recommend.
#subnet 10.254.239.32 netmask 255.255.255.224 {
# range dynamic-bootp 10.254.239.40 10.254.239.60;
# option broadcast-address 10.254.239.31;
# option routers rtr-239-32-1.example.org;
#}
# A slightly different configuration for an internal subnet.
subnet 10.0.1.0 netmask 255.255.255.0 {
authoritative;
range 10.0.1.2 10.0.1.10;
# option domain-name-servers ns1.internal.example.org;
option domain-name "local.pupyshev.local";
option subnet-mask 255.255.255.0;
option routers 10.0.1.0;
option broadcast-address 10.0.1.255;
default-lease-time 600;
max-lease-time 7200;
# allocated dynamically (if possible), but the host-specific information
isc-dhcp-server settings:
INTERFACESv4="ets32"
Settings: /etc/netplan
50-cloud-init.yaml:
network:
ethernets:
ens32:
addresses:
- 10.0 .1.1/24
dhcp4: false
gateway4: 10.0.1.1
nameservers:

ens33:

Answer 1

What confuses you? The impossibility of translating the phrase "no subnet declarations"? We read the documentation, write a description of the subnet, specify the necessary parameters.
JFYI: dhcpd only knows dhcpd.conf, it doesn't care about any other files at all.

Answer 2

option routers 10.0.1.0;

- here in dhcp correct the gateway address to 10.0.1.1
