As we draw closer to the end of our Top 10 RouterOS config mistakes, let’s look at the mistakes ranked 4 & 3

4-Bridge issues

A network bridge is a computer networking device that creates a single aggregate network from multiple communication networks or network segments. This function is called network bridging.  In the OSI model, bridging is performed in the first two layers, below the network layer (layer 3).

The biggest mistake people make with bridges is when they bridge external and LAN lines. This allows anyone that is on the external LAN IP range to have access to your internal network. DHCP can also be distributed to devices that are not supposed to be on your network.

3 - PoE issues

The PoE gets connected to the incorrect port and blows the Router’s port.
