    masalah distribusi ip publik dgn vlan

    topologi jaringan
    rb1100----wirelles wds----rb450g----wirelles wds----client

    set di rb1100

    port1 rb1100 = public ip/28 (ip tdk di buat)
    port2 rb1100 = ke rb450g
    port2 rb1100 = vlan1 dgn id= 99

    -port1 publik sdh di bridge dgn vlan1 dan use firewall
    -membuat rule di nat dgn action=accept utk ip publik yg lewat melalui vlan

    set di rb450g

    port1 = publik (dri rb1100)
    port1 = vlan1 dgn id= 99
    port2 = client

    - vlan1 di bridge dgn port2

    set di client

    set ip publik /28

    hasilnya:

    client konek ke internet dgn ip publik dan tdk ada masalah.(ip sdh terlihat di speedtest dan whatmyip)

    problem:

    ip publik yg sdh di buat di client tdk bisa di akses/remot/ping dri luar.

    kira-kira dimana masalah nya? mohon di bantu dong.Click here to enlarge

    di menu bridge anda bisa menggunakan bridge-nat dimana bridge-nat ini akan melakukan NAT pada bridge yang anda sudah buat konsep bridge nat kurang lebih sama seperti NAT hanya saja yang anda NAT adalah port yang sudah anda bridge, chek di bagian opsi bridge Click here to enlarge

    baru perhatiin baek2 vlan di eth3 dan di bridge dengan eth2 dan eth2 ga ada ip trus menuju ke switch, dan ada NAT, ini nat yg dimaksudkan adalah src-nat/masquerade? btw ip public ini apakah anda sudah paham cara penggunaannya? dari sisi upstreamer sudah meroutingkan ip public ini ke network anda? ada bgp? karena secara ngelihat sekilas jika anda pengen ip public tersebut bisa diakses dari luar maka sisi upstreamer perlu meroutingkan ip tersebut atau anda perlu mengadvertise bgp (jika anda punya asn) ke sisi upstreamer
