[MIKROTIK] LOAD BALANCE NTH ver + External Proxy (Squid)

Port 1 : ISP A --> IP Public
Port 2 : ISP B --> IP Public
Port 3 : LAN --> 192.168.88.1/28
Port 4 : RT/RW atau HotSpot --> 192.168.66.10/28
Port 5 : Proxy --> 192.168.44.1/30 

What i want is, LAN & RT/RW bisa masuk proxy dan LB bareng serta kena cache proxy, so thiz is should be

ADDRESS LIST
/IP Firewall Address List
add list="Proxy Allowed" address=192.168.88.0/28
add list="Proxy Allowed" address=192.168.66.0/28

NAT
/IP NAT add chain=srcnat out-interface=ISP-A action=masquerade
/IP NAT add chain=srcnat out-interface=ISP-B action=masquerade
/IP NAT add chain=dstnat protocol=tcp dst-port=80,81,8080,3128 src-address-list="Proxy Allowed" action=dstnat to-address=192.168.44.2 to-port=3128

Notes : karena ada 2 interface jadi kita deteksi pake IP di src-address-list
