Setting up a network with Mikrotik

montcer9012 · Wed Sep 20, 2017 8:26 pm

Hello. Help!

I am setting up a network in my office, or at least trying to, with a Mikrotik aHP-Lite 941-2nd, WebFig 6.32.2, and my current problem is that I want the Mikrotik to join together 2 internet connections into 1, so I can take advantage of two internet connections that I have. A friend told me that I have to set two ports in the Mikrotik as WAN instead of LAN, and then plug the Modems there, but WebFig is too complicated for me.

So, how can I do that? I have tried to follow some tutorials I see on the web, but my WebFig is totally different of the ones used in the tutorials so I do not understand what I am doing.

Looking forward to hearing from you.

Regards.

EDIT: On several tutorials over the internet, people uses some IP numbers, but it is not clear to me if I have to change those for my IP's, or if I have to let the instructions as they are, without any change.
PD: Sorry for my bad english

The config is quite conplicate for a beginner with no network knowledge. 1 wan is easy to setup with webfig. The second one needs to change the configuration through cli or winbox with policy routing.

Oh, I see. Well, I am trying my best with it

At this very moment, I am trying to understand this tutorial: https://wiki.mikrotik.com/wiki/Manual:PCC

I have several doubts about it; I hope someone answer here to clarify the process hahaha.

EDIT: What should I place in broadcast? (add address=10.111.0.2/24 network=10.111.0.0 broadcast=10.111.0.255 interface=ISP1) I think it is reserved for the subnet mask, 255.255.255.0, right?

Hello darkprocess,

Thanks for your answers!

Could you please tell me if all this is enough:

/ ip address
add address=192.168.0.1/24 network=192.168.0.0 broadcast=192.168.0.255 interface=LAN
add address=10.111.0.2/24 network=10.111.0.0 broadcast=10.111.0.255 interface=ISP1
add address=10.112.0.2/24 network=10.112.0.0 broadcast=10.112.0.255 interface=ISP2

/ ip firewall mangle
add chain=prerouting dst-address=10.111.0.0/24  action=accept in-interface=LAN
add chain=prerouting dst-address=10.112.0.0/24  action=accept in-interface=LAN
add chain=prerouting in-interface=ISP1 connection-mark=no-mark action=mark-connection \
    new-connection-mark=ISP1_conn
add chain=prerouting in-interface=ISP2 connection-mark=no-mark action=mark-connection \ 
    new-connection-mark=ISP2_conn
add chain=prerouting  in-interface=LAN connection-mark=no-mark dst-address-type=!local \
    per-connection-classifier=both-addresses:2/0 action=mark-connection new-connection-mark=ISP1_conn 
add chain=prerouting  in-interface=LAN connection-mark=no-mark dst-address-type=!local \ 
    per-connection-classifier=both-addresses:2/1 action=mark-connection new-connection-mark=ISP2_conn
add chain=prerouting connection-mark=ISP1_conn in-interface=LAN action=mark-routing \ 
    new-routing-mark=to_ISP1
add chain=prerouting connection-mark=ISP2_conn in-interface=LAN action=mark-routing \
    new-routing-mark=to_ISP2
add chain=output connection-mark=ISP1_conn action=mark-routing new-routing-mark=to_ISP1     
add chain=output connection-mark=ISP2_conn action=mark-routing new-routing-mark=to_ISP2

/ ip route
add dst-address=0.0.0.0/0 gateway=10.111.0.1 routing-mark=to_ISP1 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=10.112.0.1 routing-mark=to_ISP2 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=10.111.0.1 distance=1 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=10.112.0.1 distance=2 check-gateway=ping

/ ip firewall nat 
add chain=srcnat out-interface=ISP1 action=masquerade
add chain=srcnat out-interface=ISP2 action=masquerade

If so, I think I can handle. Will be difficult but is not so extensive adknowledge to obtain. I am currently going through it step by step, but I surely could use a hand

EDIT: Now I can't access to WebFig because the default gateway has changed to the one provided by my ISP, as well as the ISP. I mean, the router changed the IP and the Default Gateway and now I can't access to it neither by Wireless nor by LAN.

Hello!

I have followed this tutorial, but have not worked for me

I also tried to follow this Wiki article with no luck.

I know this is very easy for someone who knows what he is doing hahaha, but it is not my case.

Please, someone point me in the right direction!

Post your current config (filter, mangle, routes)

I hope here is all we need to check (as result of export file=my-backup):

This config is the result of a factory reboot I perform as with this config the router at least broadcast SSID with internet, and the 3 LAN ports works for any computer I connect directly. I have not stated yet, but the network I want to install is this one (please, see link to the image at my OneDrive, or the attached PDF here

EJ1.pdf

)

EDIT: It does not matter if the printer is connected to the Mykrotyk or the other router, as I just need it working. Also, I think that the switch is a DHCP server, right?

I see no load balancing in your configuration so i can't tell whats wrong

Easiest way to archieve balancing is to specify multiple gateways in default route
Something like that:
/ ip route
add dst-address=0.0.0.0/0 gateway=10.111.0.1,10.112.0.1 check-gateway=ping
