Redirect all traffic to Proxy, how to implement?

Question

network hardware

There is a goal that all computers on the network go through a proxy. Set up each, it's a long time. I have a router with OpenWRT firmware. Can you suggest how to implement it.

Answer 1

if there is a DHCP server on the network, then use WPAD - dhcp-option=252 .

Answer 2

Impossible (practically) without tweaking each computer. Use domain policies to apply settings centrally, or use ansible
