5 Port Router?
Since a Mikrotik (example being a 750GL) is a true 5 port router and
not just a consumer-grade router (which is actually a router with 4 port
switch), you can set them up to run multiple networks, use multiple
ISPs for WAN failover, and more. Why you would want to do any of
these things is beyond the scope of this post, but this will show you
how to do it.
Lets take an RB750GL and have it run 4 internal networks instead of
one. Like this:
Master Port
Out of the box, the 750 is set up for ether1 to be the WAN port and
ether2, ether3, ether4, and ether5 to be your LAN port. The reason

these 4 ports all work together is because ether2 has all of the LAN
settings and DHCP server, then ether3, 4, and 5 are all slaves of
ether2. In Mikrotik terms, ether3, 4, and 5 have their Master Port set
to ether2. The ports are even name as such, and there is an S in the
left column showing which ports are slaves:
If we want ether3-5 to run separate networks, we need to set them to
have NO Master Port. Its important to note that the Name of the
interface will not change based on your settings. If you change ether3
from a Slave to a Master, the name will not update on its own. Its just
a name. You could call it Port 3 or Fred or I have my NAS plugged in
here. It doesnt really matter to the functionality of the router Dont
get confused by the port names when you start making changes.
Change the Master Port on ether3, 4, and 5 like this (and change the
interfaces name if you like):
When youve set up ether3-5 to have no Master Port, none of the ports
should show an S in the left column.

Now, for a port to run its own network, it needs a few things:
IP Address
DHCP Server
Route
IP Addresses
To give each port its own IP address, go into IP, then Addresses. Click
the +, type in the Address you want to give the port, type in the
Network you want to assign to the port, and select the port from the
Interface drop-down menu. To set up the 192.168.3.xyz subnet on
ether3, it would look like this:
When all 4 subnets are set up, your Address List screen should look
similar to this (ether3, 4, and 5 are in italics because there is nothing
plugged into them):

http://networkingforintegrators.com/2013/01/how-to-run-multiple-networks-from-a-mikrotik/ 4/18
Next is to set up a DHCP server for each port. Its the same concept as
changing the default DHCP range, but youre just adding additional
DHCP servers and IP Pools for your network to use.
First set up the additional IP Pools youre going to use for each server.
Youll want to do this first so that when youre setting up the new DHCP
Server you can just select the new IP Pool from the drop-down instead
of having to close it, go back and create the new Pool, then go back to
creating the new DHCP server.
Go to IP / Pool and click the +. Name the Pool whatever you want (like
pool1 for the .1 subnet, pool2 for the .2 subnet, or whatever you find
easy to remember). Then enter the Addresses as the DHCP range you
want to use for that port so for the .3 subnet you may want
something like 192.168.3.50-192.168.3.100.
Do this for each port and your Pool screen should look something like
this (I have a VPN pool set up as well, and my default-dhcp was already
set up and I didnt want to change it just for these screenshots):
At this point those IP Pools arent being used by anything. You have to
set up new DHCP Servers to use them.

http://networkingforintegrators.com/2013/01/how-to-run-multiple-networks-from-a-mikrotik/ 5/18
Go to IP / DHCP Server / DHCP and click the +. Name the new server
whatever you like, set the Interface to the port you want to have use
this server, and set the Address Pool you want this Server to draw
from. In other words
Do this for each port and your DHCP Server screen should look
something like this:
Next you have to set up your DHCP Networks, so that each DHCP Client
will receive the correct DHCP information like what its Gateway and
DNS servers are. For example:

http://networkingforintegrators.com/2013/01/how-to-run-multiple-networks-from-a-mikrotik/ 6/18
After you do this for all 3 new DHCP servers (not counting the one that
was already set up on ether2), your DHCP Server / Networks screen
should look like this:
At this point, if you plug your laptop into ether3, it will grab an IP
address in the 192.168.3.xyz range. If you unplug it and plug it into
ether5, it will grab an IP address in the 192.168.5.xyz range.
Routes
Last step, which isnt really a step but you need to know about it, is
what Routes are set up for these new networks youve set up. Look at
this screenshot.
I did NOT enter any of these myself. The D in the left column means
that each Route was added Dynamically. When you set the IP
Addresses for each port, as soon as you added a new Address, the
router added a dynamically created Route for that network for you. In
this simple scenario you just need to be aware of this, you dont need
to do anything with it. Note the screenshot shows unreachable on the

http://networkingforintegrators.com/2013/01/how-to-run-multiple-networks-from-a-mikrotik/ 7/18
ports that dont have anything plugged into them.
You now have 4 LAN networks running on your Mikrotik. Since they are
all on different subnets, you will not get any broadcast traffic between
them. You can, however, reach from one subnet to another by going to
a specific IP. For example, with Control4, when you open their
programming software it picks up a broadcast that the Control4
processor sends out. If you are on a different subnet you will not see it
and the processor will never populate in the software. But, you can
manually add the IP address of the processor and it will work fine, even
if its on a different subnet. (this isnt a suggestion of how to do it, just
an example). Same goes for things like Airplay and other streaming
protocols. Many of them rely on broadcasting to tell everyone that
they are there and waiting for you to send them a music stream. This
can get rather complicated when you start trying to segment off
different parts of your networks.
This post isnt about WHY you would segment everything, just how you
could do it. :)

ether 2 gets net just fine, ether 3 gets no net but
dhcp is running right etc.
Not sure if this is a routing issue?
NAT issue?
Please help

First, check in IP / Routes and make sure
there is a route showing for each network
you have set up. There should be one for
0.0.0.0, one for the subnet you have on
ether2, and one for the subnet on ether3.

Thanks for the response.
All the routes seem to exist. Ive
attempted to recreate the DHCP
server on ether 3 etc just to make
sure I feel as though I am
understanding everything
correctly.
It seems that there is intermittant
traffic through my WIFI ap
connected on ether 3. Im not
sure why that is happening. It
seems like net access is there,
then it isnt, then there, then not
etc. It seems as well that there is
constant Rx on the interface but
no Tx
Could you help me out further?
Appreciate it!

Is there really a difference between this and a basic VLAN?
Does this route offer traffic segmentation so a network
doesnt get bogged down but still allow communication
between them?

So If I wanted to set up a Static IP for ONE particular
computer that may move from ONE network to another, all
I would do is set a Lease for EACH subnet Id pick the IP
that I would like for THAT machine on each subnet, and
instead of selecting ALL for the server when setting up the
lease, Id select the DHCP Server (that has been assigned to
that port ) and is handling that internal network .
Is that correct?
Also, if I wanted to make sure that traffic could NOT travel
from one internal network to another, how would one set
up the firewall rule?
Lastly, Id love to see how youd set up bandwidth
tracking/throttling on a per IP or MAC basis and if
possible how youd use it with THIS configuration.
These articles are the best explanation of how to use the
MikroTik routers adn Winbox I have come across. I find the
MicroTik site to be utterly useless when it comes to using
Winbox as they do everything in Terminal. They really need
to get a grip on that!
Please the NAT under
firewall.Thats what he
forgot to
include.Otherwise the
rest is ok

Nice article. How different is it to program 2 different WAN
ports not for load balancing but for specific applications?
WAN 1 = general Internet use, WAN 2 = VoIP only. When I
do it, the 2nd WAN port does not work.
Thanks

So with a firewall rule someone can isolate the traffic ? If i
connect to port 1 the wan a cable from my modem router
is it going to work ? or it is double nat ?
Well you can click the little triangle next to
Server: in the DHCP Lease window and it will
assign your IP based on one of those servers
so if you had a different DHCP server assigned to
different ports, then I would think it would see that
MAC address show up on port X so it would pull an
IP from DHCP server X. Might work. I might have
to test that out, but I cant really see how I would
use it in the real world.
To block traffic in the firewall, you would want to
set up a drop rule. For example you can say for
any traffic coming from 192.168.123.0 that is
destined for 192.168.234.0, DROP it. You can also
do it by address lists, depending on your situation.
Bandwidth throttling/queues are on the list for
some future posts..

test it out I do know dual WAN with failover can
work well on Mikrotik, so I would assume there
would be a way to do what you are looking for

If you have only cable modem, modem probably
does not NAT. If your modem is also router and
router is switched on, you have double NAT.

But, the problem is, how can I make a client on poolA IP
(Access Point) can discover another client computers

Hi,
I have a little problem.
I tried doing that on my router.
Configuration is simple, DHCP on eth2 subnet
192.168.141.0/24 with address 192.168.141.254 and
gateway 192.168.141.254 and DHCP on eth3 subnet
192.168.142.0/24 with address 192.168.142.254 and
gateway 192.168.142.254
Starting from here, everything is working fine, i get one
dhcp on one interface, and the other dhcp on the other
interface.
My problem ? if i m on a computer on the 141 network, i
cant ping one that is on the 142 ?
I got no firewall rules set so if i m right, its full accept by
defaut ?
Anyone could help me with that please?
Thanks a lot!

Having them on different subnets means that the
broadcasts arent going to travel between them
you can access the other machines, but the
broadcasts arent transmitted.
You may want to try just giving the poolB a range
in the same subnet (192.168.10.xxx) if you can.

IF you want to connect to the internet than you need to set
up Nat, so all your private ip address are translated to a 1
public ip address.

might have to get creative though. You can tell it to
not allow traffic from subnet a to subnet b, for
example, but you may find some issues with
replies from one subnet to the other.
