question about transparent proxy with parent proxy

I have a external proxy, and it works both http and https through the proxy. Now i want to do transparent proxy, so i set it as MT’s parent proxy, but only http can work, the https can not work. Any ideas? I also find this thread, seems the same problem, is it not fixed yet?

 chain=dstnat action=redirect to-ports=8080 protocol=tcp src-address=192.168.88.0/24 dst-port=80 log=no log-prefix=""
 chain=dstnat action=redirect to-ports=8080 protocol=tcp src-address=192.168.88.0/24 dst-port=443 log=no log-prefix=""




ip proxy print         
                 enabled: yes
             src-address: ::
                    port: 8080
               anonymous: no

Hey bro, how did you get the Web proxy working for HTTPs? I also redirected port 443 to 8080 like you did, but it fails to load https sites, I also tried installing a self signed ca generated on the Mikrotik device. I think you need to try to put a certificate in the www-ssl service to later forward requests to a parent proxy. I’m also trying the same, but couldn’t redirect 443 to the local proxy itself. Please help me out..

You can’t user transparent proxy with HTTPS.
Can you use GPO to force proxy settings on users?
