How can i Set Up My Mikrotik

Hello,
I’m running MikroTik 2.9.6 and I want to setup it with my ISP static Ip.
I Take the Internet from ISP with a DSL Modem.
The DSL Modem is configured with a static Ip and DNS’s, and from there the modem sends the internet to all the other computers with DHCP Server.

Can Anyone help me Pls with an example.
Let’s say that my static ip is (123.456.789.000)
My DNS’s Are (45.45.45.45 and 45.45.45.46)

Thnx in advance
Best Regards

Upgrade. 2.9.6 is out of support. Most recent stable is 4.16.

That said, the wiki manual has examples for all of that.

Hello fewi,
Im a new user, and i dont understand very well the wiki examples
Pls can you give me an example here step by step how can i do it.
THANK YOU

First, assign IP addresses. Assuming 1.1.1.2/30 for the interface called ‘WAN’ and 192.168.0.1/24 for the interface called ‘LAN’.
http://wiki.mikrotik.com/wiki/Manual:IP/Address#Example

/ip address
add address=1.1.1.2/30 interface=WAN
add address=192.168.0.1/24 interface=LAN

Then set up a default route via the ISP router at 1.1.1.1:
http://wiki.mikrotik.com/wiki/Manual:IP/Route

/ip route
add dst-address=0.0.0.0/0 gateway=1.1.1.1

Then set up the DNS servers and make the router available as a caching forwarder, assuming that 2.2.2.2 and 3.3.3.3 are public DNS servers the router can reach:
http://wiki.mikrotik.com/wiki/Manual:IP/DNS#Example

/ip dns
/ip dns
set servers=2.2.2.2,3.3.3.3 allow-remote-requests=yes

Then set up a DHCP server for 192.168.0.0/24 that hands out the router as the gateway and DNS server. 192.168.0.100 - 254 are available for DHCP:
http://wiki.mikrotik.com/wiki/Manual:IP/DHCP_Server

/ip pool
add name=dhcp-pool ranges=192.168.0.100-192.168.0.254
/ip dhcp-server
add name=dhcp interface=LAN address-pool=dhcp-pool
/ip dhcp-server network
add address=192.168.0.0/24 gateway=192.168.0.1 dns-server=192.168.0.1

Fewi Thank You
My last question
I Should put my modem in Bridge mode or I Should let it in static IP mode.

The instructions above assume you have the modem as a bridge and the static ip is set in the router. If you want to set the modem as a static ip you only really need a switch behind it (as the modem would then also take care of nat etc).
