Setting dasar RB750G



/ip address add address=192.168.1.2/24 interface=ether1 comment="To Gateway"
/ip address add address=192.168.2.1/24 interface=ether2

Setting DNS
/ip dns set primary-dns=202.134.1.10 allow-remote-requests=yes
/ip dns set secondary-dns=202.134.0.155 allow-remote-requests=yes

/ip pool add name=dhcp-pool ranges=192.168.2.2-192.168.2.254
/ip dhcp-server network add address=192.168.2.1/24 gateway=192.168.2.1 dns-server=202.134.1.10,202.134.0.155
/ip dhcp-server add name=DHCP_LAN disabled=no interface=ether2 address-pool=dhcp-pool
/ip route add gateway 192.168.1.1
/ip firerewall nat add chain=srcnat action=masquerade out-interface=ether1

Kalau menggunakan PPPoE Speedy Via Mikrotik - Modem disetting bridge
/interface pppoe-client add name="Speedy" max-mtu=1480 max-mru=1480 mrru=disabled interface=ether1 user="id 14xxxxxxxxxxxxxxxx@telkom.net" password="xxxxxxYYxx" profile=default add-default-route=yes dial-on-demand=no use-peer-dns=yes allow=pap,chap,mschap1,mschap2
/ip firerewall nat add chain=srcnat action=masquerade out-interface= Speedy

Gunakan IP firewall filter yang sederhana saja :
/ip firewall filter
add chain=forward in-interface=Ether1 out-interface=Lan dst-address=192.168.2.0/24 action=accept comment="Allow semua akses internet to client" disabled=no
add chain=input in-interface=Ether1 protocol=tcp dst-port=8291 action=accept comment="Allow Remote winbox dari Publik" disabled=no
add chain=input in-interface=Ether1 protocol=udp src-port=53 action=accept comment="Allow DNS Traffic" disabled=no
add chain=input in-interface=Ether1 protocol=icmp action=accept comment="Allow Ping Traceroute Traffic" disabled=no
add chain=input in-interface=Ether1 connection-state=new action=add-src-to-address-list address-list=spam address-list-timeout=30m comment="Log Ip Yang Di Tolak" disabled=no
add chain=input in-interface=Ether1 action=drop comment="Drop Semua Akses yang tidak di ijinkan" disabled=no

Untuk setting bandwith :
Misalnya jumlah komputer klien yang ada saat ini adalah 10 buah. Jadi harus disiapkan bandwidth itu untuk dibagikan kepada 10 klien tersebut.
/ip firewall mangle add src-address=192.168.2.0/24 action=mark-connection new-connection-mark=Clients-con chain=prerouting
/ip firewall mangle add connection-mark=Clients-con action=mark-packet new-packet-mark=Clients chain=prerouting
/queue tree add name=Clients-Download parent=ether2 packet-mark=Clients limit-at=30720 max-limit=38912
/queue tree add name=Clients-Upload parent=ether1 packet-mark=Clients limit-at=5120 max-limit=6144

Dari setting di atas sudah bisa konek keinternet
