[ask] forward to external proxy

[serangku]

i have 2 pfsense from hp t5740 spare from warehouse
first machine with 3 iinterface, wan (dhcp), lan (192.168.1.1/24) and opt1 (192.168.188.254/30, connected to iface second machine),
second machine only wan (192.168.188.253/30) interface modified with ssd sata 40 gb, planning for use squid package only

i have failed to redirect/port forward to proxy (second machine) from opt1 iface (first machine)
i have followed about redirect/port forward from doc and forum, still failed.

here my nat config on first machine
i have innclude acl for lan subnet from machine to squid conf

anyone can guide me to achieve that, redirect/port forward to external proxy ?
thanks
