How to restrict traffic through firewall, on a single cube, only to few particular sites?

@balko

I have not seen such a site yet. The “worst” is one which changes IPs each system boot.

Is tinyproxy the only solution to that?

@tripleh

Do you refer to tinyproxy from this post:

If not, can you share? I’m rather newer user.

If yes, as I mentioned it is an alternative. Don’t claim which is superior. It is more of what you are more comfortable with. And probably a more minimalistic approach.
