webproxy in mikrotik fails with firewall rules

Hi everyone:

Recently I´ve configured webproxy for seeing all URLs visited (https included with a rule. It´s like a MITM). But previosuly several devices in LAN were controled for accesing youtube, facebook and another sites. Since I´ve configured the webproxy, the firewall rules didnt work. I see in the Connection Tracking menu that router´s IP is the source IP of all traffic. I don´t know how original IPs could be checked again in the firewall rules and simultaneously work with webproxy.


Thanks in advance.


Sorry for my english!
