On what OS is it more practical to lift in Squid?

Question

Squid

Dear experts!

A task stuck in my throat that surpasses my current knowledge.
We have: a physical server with vigorous iron. On this server, 3 virtual machines are raised, united in a virtual LAN without outside access. Actually, this is a Windows terminal server and some other nonsense. On the physical server, a VPN server was also raised in order to access the virtual machines from the outside, respectively.

You need to open a terminal server on one of the virtual machines to access the network, but you don’t want to give users the freedom to rummage around the network.

Task: to raise another virtual machine in the virtual local area network, on which only Squid or pfSense will spin.

The question is: what OS to choose for this, so to speak, a proxy server / gateway, so that my brains minimally take part in sex with the settings and maintenance of this economy?

Thanks in advance to everyone who gives advice!

Answer 1

The one in which you know how to work and in which you have no questions: how to make "something" to work or how to fix a mistake. After all, you must admit that it would be stupid to raise a squid on RedHat if you don't know how it works?

Answer 2

The global answer is the one you know best. I don't know which axis you know better, but do you know which axis you know better?
pfSense is a fryaha with a web muzzle, and there is a squid there.
