RB750GL: two interfaces to the same network

Good afternoon!
I use Mikrotik RB750GL as a router between provider and my network.
My question is: how can i share two interfaces (ether2 and ether3) to the same network (192.168.10.0/24)? I need to connect separate computer to the router and this computer should see my network.
I have one range network, ether1 attached to the provider (214...).
In ip->addresses - 2 networks 192.168.10.0 for ether2 and 214.
.. for ether1.

bridge your 2 etherent ports 2 and 3
and don’t forget to change your lan ip to the bridge interface, too…

Can I bond two interfaces? Interfaces → Bond?

if i understand correct your first question of “sharing two interfaces (ether2 and ether3)”
you just have to bridge your two ethernet ports and assign your 192.168.10.0 network to the bridge interface.

If you want an extra port on the same network LAN subnet you can use the Atheros 8327 chip features.

e.g. If you leave Ether1 independent/ use for WAN, place LAN settings like IP Address DHCP server etc. on Ether2 and then set Ether 3, 4 & 5 to have Ether 2 as their master then you will effectively have 4 “LAN” ports.

The advantage of using the switch chip features is wire-speed switching.

See the following for background:

Well, I have configured the router, as you said, but after that speed in my LAN-network is becoming very low sometimes.
Even the Mikrotik’s page and RDP are loading very slowly…

That’s what I did:
[ivanov@MikroTik] /interface bridge> print

0 R name=“bridge1” mtu=1500 l2mtu=1598 arp=enabled
