    Internet ---> Modem --------------> SWITCH HUB ------------> CLIENT
    ______________IP : 110.139.61.143___________________________IP 192.168.10.XXX
    ______________GW : 192.168.10.10 ___________________________Gateway : 192.168.10.10
    ______________Primary DNS 125.160.4.82
    ______________Secondary DNS 125.160.2.34


    Windows Menggunakan DHCP

    Dimana posisi linux gue adalah salah satu dari client tersebut dengan IP
    192.168.10.110 dan gateway 192.168.10.10

    begini

    INTERNET ----- MODEM ---- CLIENT


    MODEM punya 2 interface
    1 di sisi external mengarah ke internet
    1 lagi di sisi internal

    masing2 interface punya IP, tolong koreksi yg ini
    IP external 110.139.61.143
    IP internal 192.168.10.10

    gateway si MODEM adalah IP ROUTER punya ISP, ini belum disebutkan di diagram di atas


    nah, giliran si client default gatewaynya mengarah ke IP internal si MODEM

    berarti si MODEM gatewaynya 110.139.60.1 bukan 192.168.10.10

    cek juga fitur si MODEM kalau ada konfigurasi bertema NAT (Network Address Translation), pastikan NAT-nya aktif

    sebenarnya ini jaringan sudah berjalan dengan baik. permasalahannya adalah, ketika aku mau nambah client, dan client tersebut kebetulan slackware. selama ini client semuanya windows dan berjalan dengan normal.

    Jadi aku beramsumsi, tidak ada masalah dengan modem. yang salah ada konfirugasi di slackwarenya.

    boleh di cek lagi di interface internal si MODEM di bagian subnet mask-nya
    apakah sama dg yg lain (client2 di internal)

    cek juga apakah IP si slakware sudah diizinkan oleh si MODEM untuk lewat

    IP Slackware, 192.168.10.110

    kalo kosong malah gak masalah

    mantra selanjutnya

    route -n
    cat /etc/resolv.conf


    btw, dari hasil traceroute di atas, sepertinya ada sesuatu dg network interface-nya

    ada berapa network card yg aktif ?
