    Question External Proxy Ubuntu

    Di Suruh Bos bikin log akses web client nih.....

    skema

    inet
    ||
    RB433AH
    ||
    switch======External Proxy
    ||
    Client
    udah Sukses nih ceritanya, udah bisa ke log tuh akses dari client, tapi ada permasalahan nih, mohon dibantu rekan-rekan FMI (Forum Mikroti Indonesia)

    Permasalahan :
    > proxy udah bisa berjalan, beserta sarg-nya juga, tapi calamaris gak jalan, pas di
    browser diketikkan (ip_proxy/calamaris), muncul tulisan "no request found"
    kalo untuk sarg udah bisa berjalan mas smile
    > kan routernya pake rb (Mikrotik) gimana cara redirect-nya supaya jadi transparent proxy ?, gagal terus nih.

    > dimikrotik saya pasang blokir situs pake Firewall, dan udah dipasang beberapa pengecualian
    untuk beberapa ip agar bisa buka alamat tersebut, setelah di pasang proxy semua IP yang
    udah dapet pengecualian agar bisa buka tuh alamat koq jadi diblokir ya ?

    > Windows server 2008 dengan domain ex local.bla-bla.co.id dan controller.bla-bla.co.id jadi gak bisa diakses pake browser, itu kenapa ya ?, tapi kalo aksesnya pake IP itu gak ada masalah.

    Mohon Pencerahannya mas-mas

    Gan numpang nanya sekalian, Mikrotik + proxy ubuntu 11.04 (squid+unbound)

    terkadang ip proxy tidak dapat di ping dari Client akan tetapi semua sistem berjalan normal (transparent proxy tetap jalan/terlihat di akses log, unbound tetap jalan) intinya tetap bisa internetan normal seperti tidak terjadi apa, masalahnya Tools/ netwatch jadi tidak dapat difungsikan lagi karena selalu mendeteksinya "status down" dan otomatis mendisable NAT transparent proxy dan NAT redirect unboundnya.

    Kira2 permasalahnnya dimana ya gan? (Kabel mikrotik ke kmptr proxy menggunakan cross karena menggunakan straight juga sama saja, NIC menggunakan TPlink yg Gigabit / menggunakan bawaan MB juga sama saja)
