coba ini pak, saya kutip dari forum linux juga
 di mesin router
 # iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT 
--to-destination ip_squid_box:port squid
di mesin squid
# iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT  
--to-port port_squid_box

 Saudara-saudara sekalian, mohon info nya dong
 
 
 
 1.      Bagaimana caranya mengalihkan permintaan ke port 80 dari link
 internet supaya di alihkan ke mesin dengan Ip private yang menjalankan web
 server?
 2.      Pada squid dengan transparent proxy, saya menggunakan ip private,
 nah untuk iptables nya pada router saya lakukan dengan
 
 a.      Iptables -t nat -p tcp -dport 80 -j DNAT -to-destination
 192.168.0.2:3128.
 b.      Router tsb menggunakan ip public pada eth0 dan ip 192.168.0.1 pada
 eth1. squid box dengan ip 192.168.0.2
 c.      Tapi ternyata kok malah ga bisa browsing semua ya. Kenapa ya???
