Hello, total noob here, i need to change port status on ether to so i can start DhCp setup, pictures in attachments. Please help, advice…
If port is in the bridge (port is slave in your case), then DHCP should be configured on the “bridge_local” interface (not on slave port). Bridge acts as an interface.
The same is for firewall and other services. Everywhere in config should be used bridge interface (instead of slave port).
Thank you for your answer, in the meantime i managed to find that piece of information 
. But the problem is I also found the information that you dont need dhcp server if you assigned IP address on interface :/, really confused. How could i do that on bridge interface, OS version is 6.46.2 and what would happen with already assigned addresses? Thanks in advance.
Best regards.
Router should have static IP on LAN interface.
DHCP is needed for client PC’s or other network devices in LAN (which are connected to that bridge).
And only one DHCP server is allowed in the same broad-cast domain.
Configure your mikrotik like this:
Disable DHCP client in mikrotik on LAN bridge interface.
Assign for LAN bridge IP: 192.168.1.1
DHCP pool can be set to: 192.168.1.100-192.168.1.254
start DHCP server on LAN bridge to serve clients.
B.T.W:
depending from Mikrotik model (not for CCR), if you reset you router to default config - you will get proper configuration with all of bridges, DHCP and etc, you can learn from that
Very much appreciated 
, I succeded in the meantime…will take on learning as much as possible. Cheers mate
