I have a small LAN with 12 devices connected to it, ubuntu box running dnsmasq acting as a dhcp server and another ubuntu box acting as a web proxy. Is it possible to configure all of the devices in the network through the dhcp server to use this web proxy ?
You can configure your DHCP server for Web Proxy Autodiscovery Protocol:
Create a PAC file and host it on a local web server. Then have your DHCP server provide the URL of the PAC file (e.g.
http://mywebserver/proxy.pac) in DHCP option 252:
option auto-proxy-config code 252 = " http://mywebserver/proxy.pac";
