Ideally, I need ether2, ether2, ether3, ether4 and wlan1 running separately. Can you explain to me how to remove these interfaces from the bridge and make them work with step-by step explanation(I am a beginner)?

Use Winbox.

Select Bridge form menu
Select Ports
Remove each port from bridge it belongs to.
Done.

If any interface has "Master-port" set then you will not see it in the bridge as it is masked with that "master-port". It is just like the second connector ... or the third one .... if there are more interfaces with particular master-port selected. When you unset Master-port then you will have this interface "free" as you want.

Well, since I had an experience with removing wlan1 from the bridge and had no internet access from wi-fi, I thought that there should be more steps to do.

I have default configuration - bridge, ether1 - ethernet, ether2- mastered ,ether3,ether4,wlan1.

P.S I need to make Internet working also

If any of your ports has "S" letter on the left so it IS the >>"S"lave<< of some port/bridge. You need to find which one.

Ether2 - S, Ether3 - RS, Ether4- RS, Wlan1 - RS

It means that all these ports are slaves. These with "R" are also "R"unning so it means that there is cable connected to it. Master-port is "R"unning if any of it's slaves is in "R" state.

So, what I got to do after I will remove ether 1,2,3,4 and wlan1 from the bridge? Should I also delete bridge after that?

It is up to you. Without ports it is almost unusable ...
What is your plan? Could you draw it and post the drawing?

I have home ap, I don't have any serious plan) The only thing I want to achieve is to separate wlan1 from ether interfaces. It would be good also if I can to separate each ether from each other - because I don't use any home/local network. Probably I misunderstood something because I don't really know exactly what is bridge (but I have some ideas:D).

What do you mean by a "plan"?:)

What is bridge:

Why do you want to separate WiFi from other interfaces? Why do you want separate all interfaces?

Thanks for wiki:)
Ok, to make things easier - this topic is a continuation of that one:
viewtopic.php?p=610136#p610136
In the end of conversation, I was recommended to

set a (different) IP address, configure a DHCP pool, configure a DHCP network, and a DHCP server

for my wlan1. I don't really understand what exactly and in what order I should do.
I want to separate them for security reasons.

I suggest you:

1. Reset router to default config ... if it is suitable for you ... check if it works to access Internet for all interfaces.
2. Configure firewall INSIDE BRIDGE to block access to Winbox-Webconfig port in the bridge filtering section https://wiki.mikrotik.com/wiki/Manual:I ... e_Firewall instead of top level firewall as at top level you cannot check which port the packet comes from if it is part of the bridge. The source is then bridge, not particular interface.

Such configuration lets you to use all interfaces at the same level of access to the Internet, it lets you to limit/filter all traffic without thinking about different subnets/sources/interface assigments ... acces for all devices will be equally same despite medium they use ... all devices will be visible to each other (if you do not limit it manually) at the LAN side ... think about access to your NAS, TV, printer with print-server etc.

Configuring IP Firewall for bridge is the same procedure as for top level firewall ... it is just "level down". You can have more than one bridge in your LAN and then devices connected to one bridge could be filtered different way than devices in other bridge. Think about bridges with configured firewalls as of intelligent switches which limit some access at their level and pass already filtered traffic to your router. Bridge is just software based switch.

Thanks for the reply! Well, I have no experience on setting up the top-level firewall, I just use defaults. Can you explain please what I need to do to setup a firewall inside bridge?
