In Caimito we want to reduce our use of Internet bandwidth, at least for a few weeks until we can get a higher bandwidth connection.

Two ideas:
1) block certain URLs, such as YouTube,
2) throttle traffic.

Maybe only during peak traffic hours.

Looking for software to install on our gateway router we've found Tiny Proxy. Do you think it might work, and/or suggest something else?

Our gateway router is a TP-Link WDR3500 running LibreMesh from February of this year (maybe 2016.11, I'll check). We can update to the latest release of LibreMesh if that makes a difference (we plan to update sometime in the next few months).

Happy end of the Gregorian year,
