Outbound NAT in a router to send traffic to a proxy on the LAN
-
What i am trying to do is to get the firewall to force outbound traffic to use a proxy-server on LAN machine 1 if the WAN-IP is in a certain range and comes from Machine 2,3,4 in effect i want to put all google traffic through a proxy-server before sending it out again. I am told that NetFlow on a cisco router might be the answer but after reading a little bit more it seems to me that netflow is about reporting on data and not directing data. pfSence I've tried but it would not install and i want to use a router/firewall much like the Draytek i used today that offers this type of option. A Nice to have would be a box that can do DPI on SSL by using a fake CA-Certificate and man-in-middle but thats not quite so important. I know nothing about IpTables so a router with a web-interface would be nice so what one should i buy ?
