transparent proxy eksternal di mikrotik

transparent proxy eksternal di mikrotik. berikut ini langkah - langkah membuat transparent proxy eksternal di mikrotik:

Topologi:
MODEM<-->RB750G<-->Switch hub<-->Klien
                             |
                             --------> Ubuntu Squid Proxy

Asumsi:
Modem = 192.168.10.1/24
RB750G (ether1) = 192.168.10.2/24  -------> gateway ke 192.168.10.1
RB750G (ether2) = 192.168.100.1/24
RB750G (ether3) = 192.168.101.1/24
Klien = 192.168.100.2 s/d 192.168.100.254  ------> gateway ke 192.168.100.1
Ubuntu = 192.168.101.2/24 ------> gateway ke 192.168.101.1

Transparent proxy di mikrotik:
ip firewall nat add chain=dstnat protocol=tcp dst-port=80,8080,3128 in-interface=ether2 dst-address-list=!192.168.101.2 action=dst-nat to-addresses=192.168.101.2 to-ports=3128
