Internet gateway for LAN?

Question

Network administration

Good day! There was a task to organize the Internet the gateway for a local area network (+-50 computers). What is the best way to do this? In Google, the options are pfsense, ipfire, etc. But in practical use, it was not possible to configure them. The tasks before the gateway are to be able to make the rule PROHIBITED EVERYTHING EXCEPT ALLOWED (that is, allow mail for mail or a consultant for lawyers) or at least competent blocking of domains like vk.com or urls and, accordingly, full access for management to their ip addresses. Therefore, I would like something to which you can find a setup manual.

Answer 1

What are the tasks? If only routing + firewall (+ VPN + load balancing) - take a Mikrotik of the RB2011 class. If you would also like a proxy with bumping and statistics, mail, website, tweeters, whistles - take an ordinary office car, install Linux / FreeBSD.

Answer 2

If there is money, then you can look towards the Cisco FirePOWER line of the SOHO category.
