How to routing all Lan Ports between two Subnets

RouterOS Beginner Basics
1

Hallo,

I have a new Mikrotik RB2011U.

We have two Subnets:
Subnet 1: 192.168.0.0/24
Subnet 2: 192.168.10.0/24

Now I need help to configure the mikrotik that the PCs from Subnet 1 can talk with the other PCs in Subnet 2.
Each port should be able to talk to both networks.

In that thread http://forum.mikrotik.com/t/connecting-between-subnets/61302/1 said tws101 that mikrotik automatically do that, but in my config he don’t this.

I’m a Neewbie with Mikrotik and hope you can help me!

Thanks in advance!

We need more information, do you have a firewall/nat setup and what is the configuration, do you have the routes added under ip/routes are the firewalls on the computers blocking network connections from computers on other subnets etc.

Hi Guys,

I found the answer for the problem now.

My Steps:

  1. Create 2 Bridges
  2. Give each bridge a IP from the Subnet
  3. Activate RSTP bei each Bridge

At the Computers:

  1. deactivate all unused Network Connection (it doesn’t work in my configuration when more connections are active)
  2. Give the active Network Connection the IP from the Bridge from the same network for the Standard Gateway
  3. Check Firewall Settings

In my Configuration i forget to set the Standard Gateway IP.

After I set, it works correctly.

Thanks for your help!
