Mikrotik as a gateway for two networks?

Question

Mikrotik

In the office, you need to create another network, for example 192.168.2.0/24 and give it access to the Internet through mikrotik.
The current settings are such that 1 port is WAN, the remaining 4 ports are somehow interconnected, but I can’t figure out how. The master port is not registered on any interface, and in the Bridge section, all ports from 1 to 5 are in one.

How can I allocate, for example, port 5 so that it has a different ip and at the same time Internet access is preserved?

Answer 1

You need to remove the port from the master-port list.
By default, except for the first port, all other ports (3,4,5) are children of eth2.
eth2 is your master port.
Therefore, you need to remove the port from the master-port list and make your network on it.
The easiest thing in your case is to remove eth5 from the list.
If you start to remove eth2, then you will first need to remove eth 3,4,5 from the list.
Then remove the master-port from eth2, then assign eth 3 as the new master-port for 4.5.
Why is it so difficult? Well, that's how mikrotik did at one time. Everything that works at the master-port level works at the switch level. Now in the new firmware they plan to break this logic and make everything logical through the bridge. master-bridge will do everything through the switch, all other bridges will do everything through the CPU.
Now you will need to make a new bridge, hang a free port on it and configure DHCP / IP, etc., etc.
PS As always, I read fluently.

> The master port is not registered on any interface, and in the Bridge section all ports from 1 to 5 are in one.

It can be seen that you have a new firmware, and even beta. If not, then I recommend resetting the settings. Since in this case everything will work for you through the CPU.
And so exclude the port from the bridge, make another new bridge And add a new port.
