My squid proxy block it connections remote desktop of windows
In my squid.conf add port 3389 for RDP, and trying add a iptables. The iptable that I think could work is this:
iptables -t nat -A PREROUTING -i $LAN_IN -p tcp -m tcp --dport 3389 -j DNAT --to-destination
$SQUID_SERVER $LAN_IN is my outlet to the internet}
$SQUID_SERVER It is the ip of my proxy server
