ether+wireless and bridge/routed question.

RouterOS Beginner Basics

Hello all,
I have a LAN 192.168.1.1/24 behind the ether2 interface.
I have firewall rules for the ether2 interface.
I want to add wireless clients to the LAN.

What is the best configuration?

This is the one I thought to set up:

  1. Create a bridge interface (with use-ip-firewall=yes)
  2. Assign interfaces (ether2, wlan1) to the bridge
  3. Assign IP address to the bridge
  4. Create a new DHCP Server for the bridge interface
  5. Create firewall rules for the bridge interface

Is that the right configuration?

Thank you.

That sounds correct to me.
Although you probably already have IP, DHCP and firewall settings applied to ether2.
If that is the case, just move these from ether2 to the bridge, no need for duplication here.
And for the bridge the use-ip-firewall setting is not needed if your bridge would just be a logical switch.
The use-ip-firewall setting is only needed when you want to filter traffic that normally wouldn’t leave the bridge (e.g. traffic from your ether2 connected PC to a wireless device)

Yes I already have ether2 configured with: IP address, DHCP Server, firewall rules.

The only thing I need is just to:

go in /interface address - /ip dhcp-server - /ip firewall filter
and there → edit #number_entry interface

Is that correct?

Thank you for the suggestion on use-ip-firewall too.

That’s correct
