16.7 Legacy Series / Opnsense Bridge with Squid transparent problem
« on: November 25, 2016, 01:40:35 pm »
Opnsense works in bridge mode.
Squid works in transparent mode.
The http request can be filtered by squid.
BUT there is a problem, the outside web server shows the request is from the opnsense bridge interface(ip1), not from the computer(ip2) behind the bridge.
webserver <--->opnsense bridge(ip1)<--->inner computer (ip2)
How to fix this?
Let webserver finds request from ip2, as opnsense bridge is totally transparent.
