How to set up cntlm on Ubuntu to distribute to remote PCs?

Question

linux

Help setting up a proxy under cntlm on Ubuntu. In our organization, the Internet is available through a proxy, I'm trying to set up an Ubuntu PC so that other PCs can access it through it (that is, use it as a proxy server).
Locally, everything works, that is, I registered the config in cntlm and connected to Ubuntu through my local ip, there is Internet.
But when connecting from a remote machine, Internet traffic for some reason does not go. At the same time, the ip of the Ubuntu PC is pinged. The connection port used the one that was registered for the local IP in cntml.

This is what the cntlm configuration file looks like on an Ubuntu PC:

Username (здесь логин для авторизации на proxy)
Domain (здесь домен, поскольку учетка доменная)
PassNTLMv2 (ХЭШ пароля)
Proxy (IP адрес корпаративного Proxy сервера)
NoProxy localhost, 127.0.0.*, 10.*, 192.168.*
Listen 127.0.0.1:3128
Gateway yes
(ниже указаны адреса с которых будут подключаться к proxy серверу)
Allow 10.194.10.100
Allow 192.168.20.14

Answer 1

Listen 127.0.0.1:3128

Loopback....then the traffic does not go.

Answer 2

This is how a query to Google about what the address 127.0.0.1 is looks like:
Ok, Google, what is 127.0.0.1?
(Hint: 127.0.0.1 is a special address where traffic never leaves the local computer)
