Hi to everyone on this comunity.

First off, let me just say im not very experienced on mikrotik, but are amazed of its capabilities. And sorry in advanced if this is in another topic, but I trully could not find how to get this done, even if its possible.

So, here is my situation, Ive got my office network setup in this way.

Internet Modem ISP 1 -> RB 750Gr3 -> Switch
Internet Modem ISP 2 -> RB 750Gr3 -> Unifi AP

Now, my problem is the following, I need both LAN's to see each other, or at least a specific adress list, but have different gateways, so I can seperate the traffic..
The reason why im doing this is the bandwidth of the 2 ISP's. Now then, I could go for load balancing and fail over, in wich case, I already got the fail over working, but not the balancing.

Ill be atacching a picture of the diagram to all this, for further understanding.

All the adresses used are just made up, so feel free to use your own.

The kind of guidence im looking for is and explanation of how its done, in any of the 2 cases, so I can understand the workaround, rather than just copying and pasting it.

Thanks to everyone.

Hello Kathos and welcome to the wonderful world of Mikrotik.

There are a couple of alternatives that you could choose from, but I recommend starting out with PCC and tweaking the solution to fit your use case.

Thanks Aldo, kind for your reply, that exact manual I have been tackling during the past days, and made some progress.. Fail Over working and load balancing "seems" to be working.. but i'm not quite sure..
Any specific test I could run to ensure it is working as it should?

Thanks.. =)
