Hi dev ,
when i use socks5 client on my pc to connect to squid proxy on centos  , i can tunnel RDP traffic using squid .

recently when i changed to pfsense , 
I’m unable to use RDP  using proxy .

MY CACHE PEER proxy is 10.12.0.32 , if  i use it directly i can use RDP.

but RDP from pfsense always forbidden and i already allowed rdp port in the ports in pfsense squid config .!

i will paste my squid config below and the error i face when i try .
