I setup a Mikrotik box(RB333) with 3 ethernet interfaces. Its setup as a transparent bridge on two interfaces. Then I set /interface bridge set use-ip-firewall=yes. It bridges traffic fine.

I then gave the third interface an IP and route for Internet access on a different less congested network.

I want to redirect all TCP port 80 traffic to the Mikrotik IP proxy. I then want the http traffic to flow over the third less congested interface without much disruption of the bridged traffic. So I created a DST-NAT rule that REDIRECTS all http traffic to the IP proxy. The DST-NAT rule has its counter increasing like its working but the IP proxy never sees any of it. The IP proxy is working because I can manually enter it in my browser and it works.

What is going wrong here? I have setup transparent proxies before using Mikrotik without any issues but this is first time using a bridged interface.

Any ideas?

No one has done a transparent http proxy on a bridge yet? Still not able to make this work.

I too am having the same problem - the manual says its possible to run a transparent proxy on bridged interfaces but it doesn't work.

Can anyone help?

I could do that but using SQUID as a dedicated server in bridge mode, and you will get a minimum 55% Cache hits.
