    {Help} - Mikrotik gagal Koneksi ke Internet

    Topologi
    Click here to enlarge

    IP Route
    Code:
     #     DST-ADDRESS        PREF-SRC        G GATEWAY         DISTANCE INTERFACE
     0 ADC 192.168.1.0/24     192.168.1.234                              wired    
     1 ADC 192.168.123.0/24   192.168.123.234                            wireless 
     2 A S 0.0.0.0/0                          r 192.168.123.1   1        wireless
    NAT
    Code:
     0   chain=srcnat out-interface=wireless action=masquerade
    Keadaan:
    1. Ping dari Mikrotik ke Router bisa, ke internet time out.
    2. cl1 & cl2 bisa konek ke internet.
    3. Ping dari cl1/cl2 ke 192.168.1.234 time out.

    Apa yang salah? Please Master Mikrotik kasih tau!

    Thanks in Advance!

    coba jawab
    1. dns apakah sudah diset?
    cek di mikrotik. gatewaynya apakah sudah si router?
    3. in ipasti tidak bisa, karena ip 192.168.1.234 disetting masquarade. yang mana ip dibawahnya adalah ip private, atau tidak ada route ke ip ini.

    terima kasih

    DNS sudah di set dan jalan dengan baik.

    Contoh:
    >ping google.com
    64.233.187.99 ping timeout
    64.233.187.99 ping timeout
    64.233.187.99 ping timeout



    3. in ipasti tidak bisa, karena ip 192.168.1.234 disetting masquarade. yang mana ip dibawahnya adalah ip private, atau tidak ada route ke ip ini.
    Static route untuk alamat 192.168.1.0/24 sudah dimasukkan di Router, harusnya bisa di ping.

    Thanks...!

    coba cek hasil trace route nya?
    - cek traceroute/tracert dari cl1 ke ip 192.168.1.234
    - cek traceroute/tracert dari 192.168.1.234 ke google.com
    pastekan kesini.
    di router apakah sudah diset routenya ke gatewaynya mikrotik??

    terima kasih

    ok, sbntr, ip ap 192.168.123.2 disetting sebagai apa?
    kalo disetting sbeagai NAT otomatis nggak akan bisa konnek. karena AP itu memiliki 2 ip address, 1 di lannya(WAN-nya ap) dan 1 lagi wirelessnya.
    kalo disetting bridge AP, skema ini bisa dipakai, kalo nat tidak akan bisa.

    ping yang dari cl1 tentu menghasilkan RTO, karena tidak ada routingnya kesitu.router memeliki gateway hanya keinternet, sedangkan ip 192.168.1.234 berada diluar routing dari router. sehingga router tidak tahu harus dikemanakan.

    *kalo disetting nat, ip wireless harusnya beda dengan ip 192.168.123.xxx
    contoh:
    router ---------Wan AP ->>>>>>AP Wlan---------- Wlan --- MT
    192.168.123.1 192.168.123.2 192.168.10.1 192.168.10.2, gateway 192.168.10.1


    terima kasih

    192.168.123.2 adalah radio sebagai bridge.

    Kalau gateway Mikrotik01 dirubah menjadi: 192.168.1.250, dapat konek ke internet dengan baik, dimana kemungkinan salahnya?

    Thanks!

    sorry bro,
    ok, coba dibalik bro. posisi:
    192.168.1.3 => 192.168.123.234
    192.168.123.234 => 192.168.1.234
    192.168.1.234 => 192.168.123.x(terserah)
    modelnya dirubah hihihihihi:
    -----((A))---- HUB --- LAN [MT] ----- ((MT AP))
    dirubah ke
    -----((AP))---- [MT] LAN --- HUB ----- ((MT AP))

    kalo kesulitan begini saja mudahnya.
    coba taruh sebuah client wireless dengan mengambil dari bridge AP (192.168.123.2) apakah bisa jalan. jika tidak bisa ada kemungkinan AP nya yang ada masalah.

    terima kasih

    coba dulu pakai laptop untu konek ke ap bridgenya yang 192.168.123.2
    jika bisa konnek dan bisa browsing berarti ada masalah di wlannya mikrotik

    semoga membantu
    terima kasih
