Mikrotik Router Board RB-751G 2Hnd configured as a router with access point
This example is carried out to RB-751G 2Hnd
- Ether1 will be set as "WAN" that connects to the modem or router from your ISP through "DHCP client".
- Ether2 to ether5 will be configured as a switch to not overload the router board of the CPU.
- A bridge will be created with the gates ether2 which master is ether3, 4, 5 and WLAN1.
- The bridge is created an IP range and configure a DHCP server.
- The WAN and LAN interfaces will be masked from each other by NAT.
- The access point will be secured with WPA and WPA2
Attention! You can interfaces ether2 to ether5 just stabbing in the bridge but from the router CPU board is fully loaded with heavy data traffic and network performance goes down.
Benaam interfaces to get a clear picture of what needs to be connected to which interface. Click on "interfaces" and double-click each interface. Give each interface an appropriate name.

- To "address" specify an IP address, for example 192.168.100.1/24
- Under "Interface" "bridge-lan."
- Click "OK".
You should now see two IP addresses. Those obtained from the provider and that you have created.
Configure DHCP server.

"DNS servers" fill your chosen DNS server IP addresses, for example those of your provider. Click on the arrow at the bottom to add a second DNS server (recommended). Sometimes these are added automatically. Click "next".
With "lease time" (this is the time that the DHCP server will reserve the IP address to a specific PC) the institution let alone whether to change it, click on "next".
The DHCP server is fully configured.
Configure wet settings
- Click "ip"
- Then "firewall
- Click on the tab "NAT"
- Click on the blue cross to create a nat rule.
- In "chain" slecteer "srcnat"
